Hi guys, I just recently set up my new tank, (12 gallon fluval edge). I initially added live sand, about 12 pounds of live rock, and then filled it with tap water. In the tap water I used Instant Ocean water conditioner and instant ocean salt. The tank has now been sitting for about 4 days. Today I was surprised with an RODI unit, so my question is should I completely empty the tank and refill with the clean saltwater, or should I start doing water changes every couple days until all the tap water has been replaced? What would you all recommend is the best course of action? Thanks in advance!
