Hey Mark. I think I have a 5000 at home you can have or maybe I can trade you for a frag or two
I'll check to see if it's a 5000 when I get home tonight. That being said... Im running the reef octopus recirculating ext 200 in sump and gotta say it is impressive. Set it and forget it. Not at all finicky. I can feed fish or dose my tank and it just keeps on doing its thing. No foaming over... nothing. It may be a good time for something a little newer
