    Hello. I just went to Spectrapure site and I can not find any DI resin any more other than mixed-bed. No more MaxCap or Silica Buster, other than in cartridges, which is way too expensive. Does anybody know what happened ?

    I was wondering if anybody would be able to assist me in selecting a pump to use with my bulk reef supply 75gpd RO/DI unit. What I'm trying to do is extend the life of my DI resin. I want to run my RO water into a container, let it gas off for a few days, then pump it through the DI canister...

I wonder if anyone can make a recommendation which one is better - BRS vs. SpectraPure and which type of SpectraPure resin should I use ? I have SpectraPure RO unit with...

    So I've had my RO/DI unit for 9 months now. We've got very high TDS in our tapwater here, about 600. Recently I've noticed that my RO/DI is coming out at 28 TDS. It's always been 0 before. Crazy thing is if I bypass my DI resin and test the water from the membrane it is coming out 9 TDS. So...
