You’ve been so helpful thank you so much. Still not sure how to proceed so I’d like your thoughts, if you wouldn’t mind, put yourself in my shoes for a moment:
Found a Red Sea Max S-400 at a great deal used locally, love the tank but the sump seems kinda limiting? It doesn’t have a wall to have a separate skimmer chamber and refugium, and also, according to the Red Sea website, it’s not compatible with the reefmats. I’m thinking I can MAYBE modify it to use a reef factory smart roller M, and then find some kinda way to DIY a refugium, but still, at first glance it would appear that just upgrading to a platinum 20C would solve both issues with no major tinkering on my end. But, sounds like the roller fails on the platinums. So would you find a way to mod in the roller and refugium instead?
