Get two kessil a150w. I want one so bad but Im not sure if one will be enough on a 30 inch tank
I have also been looking at Rapid LED par38s which have warm and cool whites but Im not sure the balance.
If I was super rich I would just get a radion because that thing is amazing!
Either way a good LED set up is gonna run 300 - 500 and I prefer the finished look of these products over DIY. Plus I am not good at DIYing
Heres a kessil in action this tank is awesome! https://www.youtube.com/watch?v=UP8mjsR-O-I
