Don't worry about the cycle of the qt
. Just take out as much water as you can, and use new mixed sw
for the rest. You are not going to have much of a biological filtration in your qt
anyway when treating for a desiese or parasite. When you are introducing new fish to your tank and you qt
it is good to have a cycled qt
. But using meds like cupramine will hinder the growth of beneficial bacteria. You will have to do like us all, water changes very often, and constant monitoring of water parimeters. There is no easy way around it. We all have done it, are doing it, and will do it. If you have a seeded sponge in the main, it can help.
After you are done treating the fish with the med, then you can work towards your qt
being cycled. The cupramine treatmet last about 14 days, then the fish will need to remain in the qt
for at least 4 more weeks if there are no signs of the parasite.
It is work, but it is worth it, and you can do it!
would be ok if you were not going to treat for ich, but the only thing
you need in your qt
fittings for the fish to hide, and eventually some bacteria will build on them.
