I was looking for a thread or website that explains what kind of LED lights i can use on my 90 gallon tank. I tried searching thru this website but cant find one that seems to help me. I saw a Fluval 46 watt with 620 leds that claims to be for corals for $289 at petco and wasnt sure if two of those would be enough to reach the bottom. We have LPS, SPS, softys and fish. Thank you
