I maintain a mature (march 2021) 175 gallon (662 liters) planted tank in my living room that is 36.5 inches deep (93 cm). I use 3 led light strips fluval plant 3.0, co2 injection with co2 arts stuff, of course. I get my co2 from my local beer craft place in Brooklyn, 5 pounds lasts me about 6 weeks usually. I have tons of crypts, red broadleaf ludwegia, a lot of super rare buce, a huge African water fern, many anubias, mystery snails & nerites galore. Love this tank. Wanted to send video but not option.
