I'm at a loss with this one. Two months ago, I sent in an ICP that for the first time registered 1.2ppm PO4. For the last 1.5 years I could barely keep PO4 above .01ppm. Long story extremely short, I traced it back to my RODI unit. I immediately replaced all four AL twist in cartridges, and still registered high PO4. I added three more DI canisters that follow BRS Parts 1-3, where 2 and 3 are supposed to strip out PO4, and a media reactor running seachem phosguard. Results still registering over 1ppm PO4, and I cannot for the life of me figure out why.
Measured tap, from RODI unit before container, and out of the container, all mixed with salt, not mixed with salt, and got the same results each time.
I feel like my tank is a ticking timebomb with this much PO4 going into it daily through the ATO. Any help or incite into this would be greatly appreciated.
