hey, I got a question I got a terrarium 1 and a half years ago for x-mas and know I got another one only this one is a 30-35gallon fish tank and I got 2 florisint lights what do I put on top of the fish tank so the flourisint light waves can go throw soo then they will hit the plants because flourisnt lights can go throw plast glass what else should I use to put on top of the tank so the flourist would work for the cps that I have.
