I just don't have the quarantine setup and would rather go with pre quarantine or just not worry about another fish.Ive used dr. Reef and TSMaquatics. Was much more impressed with tsmaquatics. I just used a 20g long for qt. Copper power, metroplex, and prazi. I hate prazi though. If something is going to die its usually right after prazi. I would use general cure instead. Also heard the prazi powder isnt as bad as the liquid.
