This is going to be a weird doubt
I don’t keep surface agitation very high in my tank , mainly because it has an overflow & I find the returns pointed downwards keep the substrate much cleaner than the returns pointed upwards
I have 2 returns
One on the front left & other other on the back right , both pointed downwards,
This dosent let any debris settle & pushes everything into the overflow
The overflow is connected to a DIY sump , kept outside the house , which is basically 3 HDPE barrels (120 ltrs /30 gallons each)
The way the sump is designed ., there is hardly any surface movement in the sump too , all the outlets of the barrels are pushed deep down the next barrel & split in such a way that even tho 6500 ltrs per hour (1700gph) is being pumped through the barrels there is absolutely no splashing at all
For oxygenation there is a large Air pump with 4 outlets in the 2nd barrel ( the bio barrel) which is on a timer & switches on after CO2 & remains on till Co2 starts
CO2 is supplied by 2 cerges type reactors , one on each return line , installed after the 3rd barrel)
I was wondering if anyone has ever experimented with injecting air in the said reactor rather than co 2, if Co2 can be dissolved I am sure so can air
All I have to do is drill an extra hole in reactor, connect a tubing to an air pump & start the same on a timer
This way I can keep the tank oxygenated probably much more that what surface agitation would do
