I'm currently in the process of setting up a 75 with a 29 sump. I've still got to build the stand, which I hope to get done this weekend. I have a new reef octopus classic 150 internal. My question is this- is it ok to "break in" the new skimmer in regular tap water with dechlorinator, or does it need to be done in saltwater? I just finished building the sump, and was water testing it with tap water, then just thought I'd kill 2 birds with 1 stone, so to speak, and set the skimmer in too.. Will this make a difference?
