Hello, I am going to set up a quarantine tank probably a small 10 gallon but what must I do to keep the thing cycled when no fish are being treated. I am going to do my very best to never have to deal with having to treat any sick fish etc ,but just in case. what SG should I keep the thing at and should I use live rock? I would treat marine ich if it were to ever happen with the low SG method. I am keeping just a small nano cube 24 and will only be keeping smaller fish. I currently do not have a quarantine set up and was thinking of just seeing if I could pay for 4 fish and see if the lfs guy would keep them quarantined and just get them all the same time would this work? thanks in advance
