i did, but i dont know what gph my model is. does it matter? and is there any brand that is better quality than others? 1 micron or 5 micron? color changing resin? choramine?
supposedly these guys make the unit, http://www.aquaticreefsystems.com/. dont know whats going on with the site, but cant seem to find any info.
The only part of your system that requires a specific GPH is your RO membrane. The sediment filter (1 micron recommended), carbon filter (cto), some have a second sediment filter (5 micron) then the RO membrane, then the DI resin.
If your filters are the standard 10" canisters then all you have to do is replace the cartridges with universal filters.
