Hi everyone, I am in desperate need of your help. About 6to 9 months ago, I found my water filter had given out on me, I was pumping phosphates (and who knows what else) into my tank. I was overtaken with algae and just about the whole tank died off. Now we had our floors done and so the tank came down - I kept the live rock in a completely dark trash can for almost a full 4 weeks. When it was time to set the tank up again, I scrubbed everything to its fullest (including the rock), put it all back together and gave it time - watching for a cylcle. I had a small one, and it cleared out and soon all my water parameters were normal again and I thought things were good. I did a water change and I added a full blown cleaner crew. However, soon after having the lights on again (for a leather coral) - that I worked up to (that is 2 hours a day for a week, then 3 hours, then 4 and so on), I once again have algae growing on everything and everywhere. I don't want a repeat of things. My water parameters seems fine, with the exception of a slightly elevated nitrate level - like .10. But no phosphates, no nitrites, no ammonia, temp is 76, specific gravity is 1.026. My tests match those of the LFS, so I think they are accurate. Do any of you have any thoughts on what might be going on? I planned to get a lawn mower blenny and see if he can do anything with it, but don't want to treat the symptoms, but rather take care of the cause. Any thoughts anyone? Things to check for, things to do, etc. Please help!
