Dang, I had to rush things a bit. The livestock that was left out of the 40 started looking rough. I had just put the rock and sand in the 25 yesterday and had to move things over today. The good news is that I have enough saltwater stockpiled to change 300% of the tank and the rock is very well cured, but new. I also haven't received my overflow or halide lamp, yet, (nor is my sump complete) but livestock well-being took precedence in this case. So far, everything looks better, surprisingly, but a bit irritated. I ended up having to use the old ATS compact fluorescents @ 2700K. Makes the whole tank look yellow, but it is surprisingly bright. Pics of the ugly yellow will come tomorrow and hopefully some living livestock.
