I plan on keeping my tank with heavy tannins, as I enjoy the look and the fish I am keeping prefer it.
I was wondering though - a great deal just came my way on a pressurized CO2 system. I am very tempted to take advantage. What I am wondering though, is if it will even have a benefit, as I am worried about trying the more difficult plants due to the tannins.
Tank: 90cm X 30cm x 50cm (36''x12''x20'')
Lighting: 2x39w T5HO.
Substrate: Soil capped with gravel.
