Took a step back today, decided not to jump OK, so heres the deal. I took a step back and may not jump just yet. The Chromis, Coral Beauty and Damsel are looking good again.. Whew.. I think I may not have treated long enough for the Flame Hawk originally, he is looking ragged and gasping again. That said, I have setuo a qt tank, but have a few questions. If I can catch him, 1.) How long do you treat a fish normally ? 2.) All I am running is a heater, Air stone, Powerhead, Mechanical Filter pad in a HOB filter. With the normal dose of meds, do you make water changes , How often ? 3.) Now, once the fish is out I will perform water change and cleaning and such. I want to keep it running for new fish bought and incase of illness, so, when you use the QT tank for new fish, do you always treat with medicine ? How long before they go to the main tank? 4.) How long to acclimate the tank before adding the Hawk ? 5.) OK, so if I keep it running for a QT tank for new fish and stuff, how do you deal with the cycle ? Or do you not worry about that? Just keep amn eye on params and change as needed ? I have the temp and PH the same. The salinity is 1.021 instead of 1.023, is that OK ? The Alkalinity is higher than the main tank, not sure why. More blue than green with the Redsea test kit. Will that be OK ? Any other tips on QT tank setup ? Thanks for all the support.
