So after leaching phos out of acid washed pukani for a year in my 800 gallon setup, it turns out that in the summer phosphates are making it through my eight stage ro/di setup.
What i thought was carbonate exhausting my anion resin may be carbonate and phos. My current setup up is 5 micron<1 micron<carbon<ro membrane> anion resin >cation resin> anion resin>mixed bed resin.
Color changing resins so i know when they are exhausted.
So HOW is phos getting through? Last reading was .25. My 1st anion cartridge is fully spent after 100 gallons but the 2nd one is still fine.
Checked phos on milwaukie mi524? And hanna low range.
Should i add dual gfo catridges? Or more anion?
I recharge anion resin with lye.. i have like 3 gallons of resin.
My sytem evoporates like 10 gallons a day.
