I have posted a few posts on this help but no answers so I will make a thread 
I need to know this... if I take a 10 gallon tank, add the water and filter from my other tanks, and the gravel from one tank ( it has way to much any ways) will this be a good already established tank? also how do I maintain it for a quarantine tank ? do I have to add a fish to keep it going so it does not crash with out fish in it? I saw a few white spots on one of my fish, so I want to put him right in it to make sure he is ok, but when he is put back in the main tank, how do I keep the tank up and running with out fish in it again?
thanks, sorry I had to make a new thread, I just never got answers to the ones I posted else where.
