I was just curious where one would get the abrasive seal kits for Dolphin pumps. Are there any online stores that carry them. I've been reading a lot about the Dolphin standard seals having problems, but the abrasive seals being satisfactory. I've already purchased the Ampmaster 2700/3200, but I'm a long way from setting up my 125 gal. My plan is to replace the standard seal with the abrasive proof seal even before its first use. Can someone help me out? Thanks!
