I’m buiding a 50g display which is almost done with the cycle. I got 2 clown fishes and placed them in the QT tank and dosed with prozipro for around 5 days now.
On day 2 and 3 I noticed a couple of white spots on one of them, the spost were there in the morning and disappeared sometime in between then and me getting back from work. No spots on days 4 and 5. I did 100% water changes every 2-3 day and sanitized the tank with H2O2 during the process.
My question is: I believe the spots were signs of ich, should I still treat them with copper powder eventhough Im not seeing the spots anymore before adding them to the main display? Also, 15 days on copper at 2.3-2.5ppm and 15 off just observing is enough?
