reefmat

Has anyone managed to find the overflow / forward length sweet spot with a Red Sea ReefMat 1200? Been running for approx. four weeks on my Red Sea Peninsula 650 and finding it impossible to tune my overflow so that it isn't either using the emergency drain or the dreaded constant overflow...

Not sure if anyone else is still waiting on this item. Ordered mid to late March. Has anyone received one of these from Saltwateraquarium, if so please share and if not, please share too!
