I'm in the process of building this tank, it's 11 gal
with built in filtration (approx 1 gal
goes into the filtration chamber)
Currently in the filter area I have black filter sponge, polyfill, activated carbon, zeolite and those huge bio balls that will be replaced with ceramic rings, the middle section will house the heater.
Background is limestone which has been underwater for 3 months now.
I just ordered my API fresh water master kit so I'll test the parameters before anything live goes in.
Not sure what I'll use for the bottom, was thinking of black sand or black gravel but that's still undecided
Any issues you see with my invention?
