Rodi/po4

[Grunt007]

I'm getting PO4 from my RO/DI unit (tds-0). The tap is putting out ~.6 po4 and the RO/DI ~.15. Should I need two DI units to get it down to 0 from .6?

ps- all filters/resin replaced regularly. approx 2 months old now.

You might want to run a phos reactor with GFO media after your DI unit.....this will be more efficient at pulling the PO4 than the DI resin and will last longer IMO. Good luck!

Do you currently run your DI rezin horizontal or verticle? Di resin works better verticle if you run it horizontal currently.
