Tank is back up to 72.7F right now. Everything is open, but I think I'll make sure I feed (soaked in garlic) extra good tonight.
On a side note, I took a water sample of tank water and my RO/DI water in in to AC last night and had them tested.
Ro/Di Po4 = ~0.15 <-- its actually more than my tank was reading.
Tank Po4 = ~ < 0.1
How do these measure with some of your readings?
My nitrates/nitrites/ammonia were all 0.
On a side note, I haven't done a significant water change in about 5 months. While I do like to brag about that, I do have a slight hair algae issue. While I was in AC lastnight, I bought a Kole Tang and have it on hold.. I hope this will eat up all the hair. Anyone have good luck with a Kole eating hair? I've heard they are one of the best.
On another side note and last one, this was about the worst shape I've seen AC's tanks in. They had several fish about to croak including a Kole tang, niger trigger, six line wrasse, yellow tang, and a few clown fish.

These were the ones that I noticed... I'm sure there were more. One of the Kole tangs had something very bad with its mouth. This one I bought looked pretty good, but I'm going to let them sit on it for a few more days before I chance it.
Thoughts on all this?
