Hello, first post here nice to meet everyone and thanks for taking the time to read this. So I have a 40 gallon cube upstairs running an older Reef Octopus 100, and I am starting a frag tank in the basement. It’s a 20 gallon long with the Fijicube AIO drop in. Currently I don’t plan to run a full sump (may change down the road), so I’m going to run a skimmer. I’ve narrowed it down to either buying a Reef Octopus BH90 and taking the 100 and moving it to the frag tank, or buying a Tunze 9004 for the frag tank leaving the 100. Which option would you do?
