Haha yes. I meant degress F. I always deal in celcius, so it was a brain fart.

My system looks fairly good now. I moved my Koi from the 10 gallon tank to the 75 gallon tank (at 76F). They seem to like it better in there (more space for the 4 of them and a pleco). I waited a week (with temperatures of 84F to give the Ich time to die) and now have 5 2-3 inch comets in the 10 gallon tank. I will keep them in here for 2 weeks and treat for Ich in a few days and at the end of the 2 week wait just as a precaution.

I added a handful of red wigglers into my hydroton bed. Some of the 2 week old seedlings are finally starting to enter a mild vegetative state and producing good looking leaves. No repeat infection from aphids it seems. So far so good.
