Hi I'm just running regular water right now in the Qt just to make sure filter and air pump is working. I'm going to add some pieces of pvc and a all black back ground. I'm running a whisper 10-30 internal power filter. I get my salt is in the mail next week so I plan on starting my cycle of the main tank then. My question is can I buy 10 gal of ocean water from the Lfs for the Qt and start my quarantine of the first couple of fish while I wait for the main display to finish it's cycle? Thank you!
