so my phosphates have been sitting at about .03-.05 consistently. I found my mixed ro/do water has .05 phosphate with my Hannah checker. Should I do anything to my ro/di system? It’s brand new maybe 50 gallons through it.

Is .05 too much phosphates I know we don’t wanna be too clean.

Phosphates in your RO/DI? Should be zero. What system do you have? Did you ever do an ICP analysis on your RO/DI? ATI Does one and I love it. I would recommend do an ATI ICP Test analysis. It's hard to determine what is going on or needed. Every water municipality different.

0.05 is the bare minimum you should have in your tank.

Assuming you are using a Hanna ULR phosphate checker keep in mind that the reading is +/- 0.03 so 0.05 is possibly very close to zero

Most happy tanks sit around 0.10 ppm.

BTW, you cannot use the Hanna checker to measure phosphate in RODI water. It only works with Salt water.

Sorry, it’s my mixed water, ro/di plus salt.

Agreed. Not only is the 0.05 ppm in the new salt water and top off water insignificant in the scheme of things, your tank phosphate value is fine and I would not be looking to lower it.
