I have been changing all of my filtration around. I got a new skimmer, wet-dry and reactor... before I had it all running off of one pump IMO not smart it was just too hard to control. So now I have a Gen-x 70 for me return and a Blueline 55 HD for my frag tank, refuge tank and canister filters with 14lbs carbon in them. And I think I’m going to go with an Eheim 1048 to supply my reactor...
