I,m curious if having an airstone in a planted tank is bad? this is my first time with live plants. I have only standard lighting 2 15w florescent and 2 blue cold cathodes I run all day w/ the lights for the little extra light and I like the color w/ it on. I got plants that I believe are low light plants and I use a liquid supplement every week or so. the plants seem healthy but I figure they're not really going to grow all that much/just sort of stay where they're at and not produce all that much oxygen. so I supplement w/ a 10 bubble wal in back. I have a whisper 60 and 40 on the tank but I keep the water return below water level to keep noise down so agitation at surface is mininmal.
