Lighting for a 90-gallon viv

[Omega]

Do you think 212 watts (4X 48" 54w T5s) would be overkill for a 90-gallon viv?

Bulbs would be Sunblaster @ 4700 lumens, 6400K, and ≥ 80 CRI from a hydroponics store. The fixture would be from a saltwater fish store.

I want to keep all the different kinds of plants you would typically find in a viv, including ferns, moss, broms, and maybe even orchids if I'm so lucky. Inhabitants will be either green-eyed tree frogs or darts.

Thanks!

I think you would be ok. Your 90 is tall so you need alot of light to really get to the bottom efficiently. I run a pair of 30" on my 65 which is the same height as your 90 and feel one extra bulb would help me acheive a better look. If its too much black out one bulb or loosen it up and run 3.

OK, sounds good, thanks!
