So this is really confusing...I'm finally setting up my RO
system again and this time around I'm going to replace the micron filter with a DI
cartridge. However my cartridges are 9 3/4" while all the DI
cartridges on Marine depot and bulkreefsupply and other places are 10"....More confusingly I googled 9 3/4" DI
cartridge and got something titled: "10" DI
Cartridge" and under the specs it says 9 3/4".
Is it that 10" cartridges are all 9 3/4"? Also my RO
system is a Five stage unit....do I really need that last water polishing stage? It's supposed to remove taste from it or whatever but from what I gather after just the prefilters, RO
and DI TDS
will hit 0.
