Is this too much light?

jefftse · #1 12/04/2007, 01:12 AM

I have a 90g and having half SPS and half LPS/Softies. Right now, I'm running 2x175MH and 110W PC. I think my lights are acting up. I don't know if the bulbs or the ballasts. Anyway, I'm thinking to change them to 2x400MH. or 400MH for SPS side and leave the 175 for LPS/Softies. Do you think I may have too much lights for a 90g?

Thanks
Jeff

2x 250w is more than enough.

250s will do the trick.

I don't think 400 watt halides are going to be that much of an advantage over 250 watt halides.

i thought about 250 but the price is like a hair more.. so I really thought to go with the next one up.

Right, but the electricity will be more and the heat will be more.

I would say go for the 250's.

2 x 250 would get my vote as well

2 x 250 would be good enough.

yep, 2x 400w on a 65g might burn up everything in your tank, unless the fixture is like 3ft above your tank!!!
