Does anyone have a refillable di cartridge that can fit a pure-flo 2 50gpd ro/di?
The coralife one that comes with it and the replacements is not refillable. The unit takes standard 10 inch parts. Do not use the kent marine line, they are a different size. Delaware Premium Aquatics sells both the coralife and also a aquatic life di that is refillable. I use the aquatic life in mine (same unit you have but now upgraded to 75gpd). You can also get them from our sponsor airwaterice.com and get club discount (bulk DI resin there too). Personally I love a trip to DPA anytime. They are on the end of the asile near the register.
Thanks for the info. Ill be looking into it.
