Has your Hanna checker ever been calibrated, mine was off quite a bit until I adjusted it with Hanna solution. Got lots if you need some.

You are concerned with the tds coming out of the ro unit.
I stole this from as desert rat on nano reef.


TDS does not necessarily mean 0 phosphates. Phosphates like silicates and forms of ammonia are weakly ionized and may not register on a hobbyist grade TDS meter, it would require a conductivity or resistivity meter to get to that level for sure.
That being said, if you are getting a reading of 0 TDS I would say its safe to assume the phosphate levels are low enough to not be a concern in the RO/DI water

i never heard of calibrating a hanna checker, im going to look it up.


i dont have a tds meter on my rodi unti, i was only using my hanna checker
