Question. I have a 46 Gallon planted tank and having some difficulties in growing and currently have a regular 30W flourescent light and a 96W coralife compact light. My question is any chance of my difficulties being because i have a glass top to the tank? I know any glass takes UV away but enough to hinder growth?

I too prefer open top tanks. I just like the ease of maintenance, feeding & not having to clean the glass. Although all fish can jump out, if you have fish that are know jumpers like Hatchet fish for example, then you would want to keep the top covered.
