QT Tank Cycle Crash??
Right after moving my two fish from my 20g to the newly cycled 40g (about two weeks ago now) I began to turn a 10g into a QT tank. I took the filter that was used for the 20g and moved it right to the 10g QT tank. I recently addws a small Cardinalfish in, so trying to do things right, I acclimated it to the QT tank first. Everything was great and the levels were good for the first several days. I began to check the levels not as often because I figured the beneficial bacteria in the filter media would handle the load of one fish.
Well I guess not. I feel like an idiot because I know better, I should have checked the levels more often, I mainly have been focused on making sure my 40g continued to stay in good shape. Today the fish is dead in the QT. Checked the levels....Ammonia is 0, Nitrite at 5ppm possibly higher, and Nitrate at 30ppm! I thought this was suppose to be an effective method of cycling a QT tank. Ugh.
Any suggestions? Right now it's still running...should I just let it cycle? How do you guys setup a QT tank with a strong bio filter? Without a cycle I'd be doing a lot of frequent water changes, and in a 10g I'm sure it will shift the levels around more then a fish would like. I figured this would be the same thing as sponge from a cycled tank into a QT tank.
Thanks. It sucks to learn things the hard way....
