I have a tank that I started late December (it's about 2 - 2 1/2 weeks old). It has 2 clowns, 1 cardinal fish, 1 chocolate chip starfish, and a handful of hermits & snails. I was wondering when I can add a blue hippo tang? Ammonia & Nitrite are 0. Nitrate was high, but then I rinsed out my fluval filter and it went back down. Phosphates are high, but I'm positive it was from overfeeding (thought I had to leave extra for the hermits & snails) and now I have Phoslock filter media in there, so it should be coming down. I have about 150lbs. of rock in there, about 1/2 live and 1/2 lace. My children and I are so excited to get Dory, especially now that we have Nemo. When can we get her?
