Hey gang! I was just wondering where you guys get your DI Resin from. I have been getting it from the filter guys but I feel there must be a better place. Is there any place I could get more and for cheaper? I'm going through this stuff way to fast maybe its time for a new membrane. Does anyone one have any idea. Also has anyone ever tried to recharge it themselves? I read a tread on reef central on how to do it but it sound risky. Thanks! Zak
