Ro unit output levels

[Exotic Reefs of NJ]

So I welcome any and all thoughts in this one cause I'm stumped. 100 gpd 6 stage ro/di unit, TDS meter reads 159 ppm input and 000 output which is perfect. Just replaced .5 micron and 2 carbon filters. Tfc membrane is less than a year old. So today after concern with phosphate in the 180 reef I checked the water coming out of the ro unit. Hanna phosphate checker shows 0.06 ppm. Open to anything you guys/girls can figure out.

You can't get an accurate phosphate reading on pure RO water.

You can't get rid of phosphate either... it's in everything. Minimize and control your phosphates by reducing/rinsing frozen foods and use chemical media (with periodic changes) to keep it in check.

159 ppm ,input , may be the problem, i got 35 ppm input on Queens, u have also DI , right ?

Does anyone use Gfo or other po4 reducing media in their rodi????

159ppm... because he lives in NJ. Not the cleanest water source at all.
