Hey all. I have two maxspect gyres xf350 from my previous 300 gallon build. I now have a Red Sea reefer 750xxl. The magnet on one of them works perfectly fine through the glass while the magnet on the second does not. I switched the magnets on each to to see what happens. The pump will hold on the left side of the tank but not on the right. Granted, the magnets don’t stick as hard as they used to on my 300. Is there a solution to this problem without having to buy new pumps? Is there perhaps a magnet upgrade available by coralvue?
