RO/DI learn from my mistake

[chi6488]

After a 1.5 yrs and probably 600 gallons I finally decided to flush my coralife ro maker. I also purchased and installed a dual stage deionizer which worked great.

I FORGOT to replumb the RO maker so it was shooting out junk from the membrane. TDS was reading 240+ and I thought it was the ro needing new filters and membrane. Needless to say I finally caught the error after about 120 gallons.

Well the RO reads about 1-2 tds but after the DI it reads in the 40-50 tds. I blew through two cannisters of di resin in a week and now waiting for the resin. I am making ro water with a with tds 1-2 right now.
