Cannot get rid of cyano!

But have to ask, if you have zero N03 and P04 why are you even using bio pellets?

This is a good question to which I have a good answer....I am stupid and impulsive! I was getting into a lot of SPS (I have around 80 SPS in my tank) and I wanted to pre-empt any nutrient problems, since I am heavily stocked and wanted to feed my tank more.

I started very slowly, with 200ml for a 125 gallon tank with a 55 gallon sump, and never had more than 500ml. I dosed bacteria and did everything I was "supposed" to do, but I got hit with cyano anyway. Unfortunately, since my nutrients were so low to begin with, I was stripping my tank to where the corals didn't like it and I couldn't seem to feed the tank enough, so i took them off line.

But I don't want to highjack the thread. I just wanted to give another experience.
