| | First planted tank! Worried about the soil depth
Hello! So this is my first foray into planted aquarium world. The plants I get from an LFS doesn't look pretty good (leggy stems, bad leaf etc) but that's all I can get. What worries me is the depth of the soil in the tank. I've read that the recommended soil thickness is about 1 inch but not thicker as it could cause the soil to become anaerobic but how about less? Are there any negative effects in doing so? I use about 2 cm of soil topped with just enough silica sand because of some miscalculation when ordering the potting soil online.
