Hi everyone,

This is my Gold fish Tank , Currently running a FX 6 filter on this (pic 01)

I’m planning to move from the FX6 to a Sump for this tank ( Maintaining a Canister filter is a bit of a pain esp. because the cabinet is not large enough to fit the FX6 properly & taking out the pipes from the FX6 is nearly impossible

I am not new to sumps , the 2nd pic is my sump on my hi-tech planted tank, but this is way too overcomplicated , mainly because 1) the water is pulled form the tank via an overflow & is fed to the sump which is kept outside the house & 2) I had to design the same in a way that there is minimum splashing to preserve the CO2 injection , the 3rd pic is the Tank in which the overflow & sump are running (7 months now)

This sump works seamlessly & serves all the intended purposes while making maintenance & water change a breeze ( literally a 15-20 min job on a tank that is 6 X2X2 ft) & I can easily get 30-35 ppm of CO2


But in this Gold fish tank , I am looking for something slightly different, I want the water to be pulled form towards the bottom of the tank & not from the top as an overflow does

Most of the debris in this tank is broken roots (thanks to the goldfishes) which are heavy enough to sink & not be pulled out form an overflow & the goldfish poop is definetly heavier than the tetra poop in the main tank

I had made this (pic 4) simple DIY solution for draining water from this tank for water changes

Basically just a simple PVC siphon , that I fill with tank water, close the valve, put the shorter end in the tank & open the valve

I was wondering if I can use a similar DIY concept to feed my sump , which in this case will be in the cabinet below

Ofcourse it will be a single pc of PVC pipe rounded at the top to ensure better flow , will have a strainer to stop really large debris entering the pipe

I wanted to know

  • If such a system will be stable in the long term , as this tank dosent really require water changes for a month or so , the plants strip of everything , I even fertilize the water collumn on a daily basis , yet have never seem any NO3,PO4 in the water & K remains modest at best ( something like 10-12 ppm) , hence the siphon will be primed only once a month, tho I can make it a point to prime it again weekly
  • Has anyone ever done something simillar & did the siphon hold long term?


Am a bit apprehensive because unlike an overflow this has no emergency drain

The entire system is on a power backup , hence not really concerned about the pump failure but more concerned about the siphon failure

Would really appreciate insights from anyone who has tried something similar.

Thanks!

When I was walking around Aquashella Chicago, I crossed paths multiple times with Logan Rando while he was filming. I was wondering if he had posted a video of the show yet so I checked out his channel. No video of Chicago yet, so I instead watched his video of New Jersey. About half way through the video, Father Fish rolls by on his scooter and announces he'll be making an announcement that will destroy the tropical fish industry. LOL! I didn't know Father Fish was actually a speaker at Aquashella. Seems funny that a guy who preaches about not giving money to the aquarium industry was invited to speak. I figured WTH, I'll bite and go to his channel to see what the big news was. I couldn't bring myself to watch the whole thing, but I did scan through it and still don't know what the big Earth shattering news was. Just the same ole preachy stuff and I regret destroying the brain cells. I have to be more careful of that, as I'm older and can't afford to lose many more. I'm sure glad my path into this hobby was seeing the work of Takashi Amano, other knowledgeable aquascapers, and all the great folks in this community.

Time to start a new thread.

I’ll fill in some details later, but I’m working on the hardscape now. Any and all criticism is appreciated. The vision is nothing more, and nothing less, than something appealing to the eye.

90cm x 30cm x 30cm Lifegard Aquatics ultra clear bookshelf tank. Buce and anubias on the hardscape, stems towards the back and center, mid to front carpet with some changes in shade and texture down to a flat grade on the right side of the tank.

Lily pipe inlet and skimmer will be in the back left corner with the outflow in the front left to hopefully achieve circular flow. I’ll be running an in-line diffuser. Light will be the P600 Pro that I regrettably did not upside to 900. Oh well. I’ll mount it high and hopefully it’ll have enough spread.

I have some dragon stone and red lava rock rubble I’ll use at the base to blend into the substrate, as well as some stratum I may or may not cap with.

Anybody else stay up late to watch the IAPLC rankings. As usual, my choices would have been different. Some scapes ranked in the 40s got picked by some judges as the best, so at least I'm not alone in that. Highest ranking by a U.S. contestant was Ryan Noel at, I believe, 31. Congrats to Ryan.

I wanted to share my experience so far with a cheap flow meter from Aliexpress.
I am generally a “you get what you pay for” aquarist, but I have taken a gamble due to circumstances. It is still early days, but it feels like it may have paid off.
Looking to add a flow meter to help tune my CO2 in a newly set up 130L tank, I searched far and wide for the different options. They were few and far between, most were for far larger flows than I needed and those that were appropriate were ridiculously expensive to get to Australia. So I went searching on the various Chinese discount sites and came across the LZB-3WB flow meters. They are cheap… real cheap. Less than $30 Australian landed, which made me nervous, but felt it was worth a shot at that price.
Not knowing what flow ranges I would need I ordered a 6-60ml/minute model.
After installing it, it was clearly too high of a range for my tank, but it did allow for some visibility while adjusting CO2. It was certainly better than a bubble counter.
Here is a picture of it action:
1774008536678.webp
As you can see, the reading is below the scale of the meter, but with a marker I could at least set a starting point as I adjusted my CO2 higher. Also the adjustment valve was useless, a tiny turn would shut the flow off or open it to max out the meter.
I ordered the below as a replacement:
1774008611064.webp

2.5-25ml/minute seems like a good range for my tank.
As a bonus the valve is better than most standard regulator needle valves. I can adjust the flow in increments of about 1ml/minute.
Below is the valve in action:
1774008809018.webp

They have been in service for 2 months total now, 1 month each, so still an early review. It has been a solid upgrade though and was an easy install. They come with big 8mm barbed fittings but they can be unscrewed to reveal 1/8 female threads that standard needle valves for aquariums fit. I have also got some 1/8 to push fit fittings that I am yet to install as I am heading away on holiday for 2 weeks soon and don’t want to make any changes for the house-sitters to potentially have to fix!
Pros: adjusting my CO2 was made so much easier by being able to see exactly how much of an increase I was making with each adjustment. Monitoring that the valve isn’t drifting has been easy also, a quick check of the meter tells me it is steady.
Cons: I doubt that the reading is accurate. This means little to me, as I am not using it for a calculation or comparison between tanks. As long as the reading is consistent, even if it is wrong, I am fine with that. Also, the max pressure is listed as 40psi. I am unsure if that is a failure or accuracy maximum. Again, it doesn’t affect me as I run a low regulator pressure due to using a reactor. If I were using a diffuser that needed a high pressure, it may make me nervous.
As always, with any cheap gear, your mileage may vary. But, I thought it was worth sharing as it may help those with limited access to flow meters of appropriate sizes. So far it is proving to be the second best $25 I have spent on this tank, second only to the super red bristlenose I have in the tank.

I want to thank @Unexpected for introducing me to this new forum, but most importantly for him being the first ever to build the Horizontal CO2 Reactor. I feel honored that "Yugang Reactor" as he calls it (Yugang 鱼缸 means fish tank) is introduced in @Unexpected journal, but it would be a pity if that journal gets cluttered with too much reactor talk. So let me open a dedicated thread for discussions, questions and help on this Horizontal Reactor.

I have been experimenting for years with CO2, and at some time I took videos of my (modified) Aquamedic reactor to watch the bubbles in slow motion. To my surprise I found that the combined surface area of the bubbles was not very high for achieving a 1.5 pH drop in my 250 liter tank, and that CO2 absorbs so fast in water that the lifetime of bubbles is quite short. So .... we don't need to juggle bubbles at all, we can just create a very simple absorption interface between flowing water and a pocket of CO2 above it. The Horizontal reactor is surprisingly simple, and has some benefits that we won't find in diffusers or conventional Cerges / Griggs bubble reactors:
  • Simple rules to find the correct dimensions for any tank, a small nano tank or a huge tank the size of a swimming pool.
  • Very easy and cheap to build with plumbing materials. No fragile parts, low risk of leakage or malfunction.
  • 100% CO2 absorption efficiency
  • No need to experiment with vortices, venturis, diffusers, needles wheels, impellers / rotors, multi stage reactors - it is just a pipe with a gentle flow of water.
  • No noise
  • No mist in the tank
  • No maintenance, and stable performance over time
  • Virtually no reduction of flow from pump
  • A purging valve is optional, as the reactor will purge itself from excessive trapped air.
  • The reactor can be configured so that in the event of a failure, CO2 injection will not exceed a limit and fish cannot be gassed. Inherently safe.
  • The reactor can be configured so that we do not need a precision regulator, because the reactor controls the CO2 injection rate

Or a multi stage version ...

I am happy to help new users to verify the calculations on reactor dimensions for their tank, please send me a PM.

Ludwigia repens, hairgrass "eleocharis palustris" and ludwigia glandulosa all found locally growing emersed beside water and all growing submerged in water. Nice freebys if they survive the transition theres 20,000 stems in this tiny little pond. all clean no bugs put in tank with no fish to be safe will peroxide dip it before moving into other tank. 1 bunch l repens last pic I picked 8 days ago grown 2" and top turning more red with no melt at all. Well see how it goes. All found beside my local Lincoln dealer parking lot lol.
I've got local emersed plants before I know where theres a storm of lemon bacopa and anacharis is. Seems it always melted badly to mush. These plants are growing emersed for a week then submersed for days when water levels go up. Maybe they are more hardy being grown above and below water over and over? They may all melt to turds in weeks lol.

Got on the tree build kick in past 2 weeks to make somthing I like for 36g freebie build to replace the huge tree turd #2 in there. I got 6 stumps ready today to get built for smaller tanks, 3 done today 3 waiting. Built the larger 17 tall 16 wide tree pics added other day to journal but gonna a build 2-3 more larger trees and the 6 smaller. Sell the ones off on eBay and etsy I don't want.
The larger stump 2nd post pic s 16" tall 15 wide plan to use in future scapes smaller. I've been using Amazon branch packs 15.00 for 25-35 pieces and amazon spiderwood 6-8" 5 for 12.00 for small trees. The large tree I made was a 10.99 piece I tore apart and used the 3 larger branches and built onto them to get the large tree in added pics cost me in end around 22.00 .... I have 10 pieces coming in mail Friday 5 large and 5 medium all spiderwood to make larger trees with this weekend.
Bought a ton of Amazon wood on Amazon lol 2 for 17.00 10-14" so I glued some of them together for larger usable pieces. some came out cool and well worth the 17.00 for the pieces glued together.The 1 has natural plant pots on top. The v shape last 2 pics 12" deep and 16" wide
After literally glueing a finger to a rock today Imao I quit! I ended up used all the accelerator I had anyway so Friday or sat before I can finish my smaller trees. will update as it goes, It will be a forest of trees when its done.

I have always liked Rotala florida as plant due to its strongly colored leaves, but realized that I haven't actually aquascaped much with it - meaning to integrate it as part of a layout and not just growing a bunch of it in farm/collector style tank. Using plants in a layout in tighter bunches, and in competition with surrounding plants/hardscape is much harder than growing it farm style in a single patch - it also means be able to shape/trim the bushes to match the overall curves of the layout.

Back in 2016 or so when I first received Rotala florida samples from north america, I could only grow it in sparser bunches. It looked nice in macro photographs but I could not envision using it an bush that would show off well as part of a layout unless I can grow it much denser. In the recent years, there were two main discoveries that I found in my experimentation, the first is that it grows better in moderate GH (5 dGH+) compared to super soft water (say <3dGH), and that it grew better in certain soil mixes (I experimented with different garden soil mixes when engineering the composition of APT Feast). Eventually I integrated some of the soil data into APT Feast's composition, and paired with the higher power lights readily available today, I find that I could finally grow the plant the way I envisioned as part of overall layout. I could prune it dense, as the base stems were healthy enough to sprout dense side shoots after trimming - and the secondary/tertiary shoot tips were as fully colored and sized similar to a primary shoot tip that hasn't been subjected to topping yet.

As a midground stem, it works very well due to its slower growth rate vs other colored stem plants.

Against the deep purple of Rotala florida, I found that Golden white clouds worked quite well. So now they are the main inhabitants of the tank.

Tank this week (25/6/2025)
2hrAquaristDSCF3912E.webp
2hrAquaristDSCF3880E.webp2hrAquaristDSCF3309E.webp

Tank started out like this:
2hrAquaristDSCF3039E.webp
A week or 2 after initial planting (5/5/2025). I reused old aquasoil from the previous scape, so I planted all plants up front rather than waiting more time for the tank to stabilize, with the idea that I could out-grow any algae issues. Initially wanted to add H. Chai but it really didn't fit the overall color scheme, and the bushes by the side were too invasive to be compatible with having a chai patch I think.

Since it was going to contain Rotala florida, I thought I might as well throw in other high demand troublesome species such as the Red Eriocaulon quinguangulare, blood vomit. I settled on Rotala tulunadensis for the background as I wanted something dense and shapeable.

Tank specs:
60x36x36cm
Filter: Oase biomaster 250, all sponge media
CO2 injected through inline atomizer
Substrate: APT Feast
Water column: APT Sky to raise GH to 5dGH, 2ml of APTe per day.

2hrAquaristDSCF3291E.webp
Light distance. Interestingly, not crazy high PAR - just around 200-250 umols PAR at the substrate level.

Name 3222E 2ft florida.webp

Trimming and shaping: Most bushes were shaped by cutting individual outlier shoots one by one. Only Rotala blood red and the Rotala tulunadensis was straight trimmed across the entire top once.

2hrAquaristDSCF331Ed5E.webp
This is how the Rotala tulunadensis looked like after a straight trim on 29/5/2025. About 3 weeks from when the top picture at top of this page was taken. It took the plant a whole week + to show new shoots. It seems straight trimming slows down the plant quite a bit, but allows for a very dense & neat canopy afterwards.


2hrAquaristDSCF4019E.webp
There are some interesting plants stuffed here and there. Some Eriocaulon caulescens? bolivia? that local hobbyists passed on to me. Carved out a patch for Syngonanthus vichada - slow grower, but the couple of babies that came have doubled in size so I think they should be alright. I think I will move them to a larger tank with more space.

Only discovered the color combination with the Golden white clouds when the tank matured, but its one of my favourite fish-plant combinations now. I think that while some of the species are a bit picky about growth conditions, one thing I really like about this tank is that most things have moderate/slow growth rates, which makes maintenance with regards to removing excess growth less tedious.
Elatine triandra is used as a low growing green filler plant - it does this role well. As it does not root very deeply, I can easily cut and pull off excess growth easily. Its the fasting growing plant in the layout that requires frequent removal of excess growth.

Some more close-ups.
