If i am setting up a quarantine tank, can i just use new water? Is there any reason to use water from my display tank? It currently has high nitrates so I am hoping that new water would be fine for a quarantine tank. I plan on using a 10 gallon tank, with just a heater, sponge filter and some hiding spots. Also since there is no live rock or anything to help with filtration, how often and what percentage water changes should be done?
