How much are you feeding, and how much live rock/live sand do you have in the tank?

Have you tested your RO water? I used to get RO water from my LFS until I tested it and found that it had a bunch of chlorine in it, seems they weren't changing their filters as much as they should.

What are those 8 fish?

Yeah, I agree w/ Toddtrex.... depending on those fish, they can have too much of a bioload or are messy eaters. How big is the sump/fuge? Got bio balls? What are the other specs of the tank?

Welcome to RC! I'm thinking Bioload issue, as well. Relationship between Livestock & Live Rock/Sand could be a good place to start. What are your parameters in totality?

Yea, I have a 75, fed once a day and I only had 5 fish and had nitrate problems. Depends on your fish, but I would say bioload. Care to share fish load? Try feeding every other day. Live rock goes a long way as a natural source of food, but you also may need to unload a fish or 2.
