wow; sounds like you have a very nice setup going towards the broodstock; when you say that your rot's do better in the garage do you mean colder temps then? I have my cultures out in the garage as well. As far as the ich i added a small pacific blue that broke out, so i removed him & placed into qt for 5 weeks of hypo treatment, during that time he bounced back & forth with showing an outbreak even at 1.006 for a whole week, right now it's just him & my filamented wrasse, the 3 chromis seem fine, everyone is eating like pigs, it's defiantly not an issue i wanted to deal with, but it's there now lol
