Went and bought 2 new stealth 250s as I don't care for the Hydor Theo ones. the 2 are keeping the tank at 85 right now they seem to be cycling between the 2 as sometimes one is hot and the other is cool and vise versa. Once the Ich is gone I should have no problem going back to running my tank at 82 with one and the other set at 79 for a backup.
