Replacing Ro/DI Filters

[ReeferRob]

I need to change out all my RO/DI filter media this week and was curious what other here on R2R are using.

BRS of course has the best prices, but the quality is suspect compared to Spectrapures. I own a Melevsreef unit, he sells replacements but there is not a lot of info on the products he is selling........what to do, what to do!!:squigglemouth:

My understanding is that there are two companies that make the RO membrane. Dow-Corning (Filmtec) is the best IMO. Are you talking about the carbon and prefilters?
