I just got back from the store I got my koi from (Wal-Mart) and when I looked at their fish I saw that some of the other fish in the tank that my Koi came from had ich! I don't know if my koi was infected or not, so I would like to treat him ASAP. My options are as follows:
1: Install the filter as planned, add salt (increasing heat isn't possible) and cross all my fingers.
2: Transfer the Koi and the three goldfish into the 20 gallon tank, put my new filter in there and aeriate the living s**t out of it (I have welding oxygen and can aeriate with that if nessasary)
Which sounds better to you guys? Bear in mind I KNOW the 20 gallon tank still has ich.
