No I’m not pluming them together I went back and forth with this but. I don’t want to have something happen that effect the entire system. With separate systems I don’t have to worry about being completely out of commission. And if I do have to treat for something It would only be in one tank and for 40gal. It will take a little more time to do maintenance but I think it’s worth the trade-off .
what are you going to use for water movement, are you going to do a refugium? are you going to run a skimmer on the systems?
