Will this work?

What if, I added in my singular housing, pre-membrane, for a total of 3 stages before water reaches the TFC. I would use a .5 micron sediment filter, then a basic carbon cartridge, then a chlorine guzzler. After that it goes through the membrane and on to the double housing unit from my extra Coralife 50 gpd unit. In those two compartments Ill put the Spectrapure Hi Capacity DI and a Refillable DI resin cartridge in the final stage. Ill get the REfillable shell and a bag of 6 resin recharges from Spectrapure.
