Ok so it sounds like if I get a tank, under 20 gallons, I'm better off going T5 for the price and for the lights/size of tank and no algae. I'm leaning towards something rimless, but a lot I don't want a small little cube. I'd like something between 10-20 gallons, rimless. I was looking at the Fluval Edge, but I've seen some complaints about that tank... such as the stock LEDs on it are pretty bad and the top opening is very small when it comes time to prune. Anyone have any input on it?
