Hey gotta few questions first one is what are some good tall plants i could plant in the back of this tank and should i keep that rock in there cause i would like to attach some plants onto it or should get some driftwood. Also I have some dwarf hairgrass in my tank but how long with that take to grow a full carpet. I have co2 running and liquid fertilizer. Anybody have any suggestion of what looks good and what i shoulddo with this tank. Recently i changed my tank to sand over from gravel cause the hairgrass was coning out so easily. Oh plus i know I know I got a aquaclear 30 for christmas dont ask how I know ha
