Just a heads up @Bulk Reef Supply , the af-rs170 fits the red sea xl 200 perfectly after cutting off about an inch on each of the overflow drain pipes. Might want to rebrand that as more than a one tank wonder. Let me know if you'd like a picture of the fit.Any AquaMaxx product you see on the BRS website is something that we plan to carry. Now it's just a matter of getting all of the AquaMaxx products processed into our warehouse and ready for shipping.
