ATO Phosphate?

[Gary Ellis]

I checked my ATO water for phosphate and it was 0.01. Is this OK?

What is your rodi water out of the system?

That’s not quite the same answer though

Immediately out of your RODI = 0.01: change your di resin

Out of your rodi and sits in your ATO container overnight=0.01? Change your ATO container for something that isn’t leaching po4, or live with it.

My TDS meter reads 0 on the out side. Is that what your looking for? When I fill the test tube with the water that comes out that's sitting in my barrel and test it with the ULR Hanna tester it read 0.01. The water is tested immediately and not over night. It's in an igloo drinking water container. My actual tank water test 0.03

Test directly out of the RODI unit before it goes into the barrel. Then compare. Either you have phosphate making it through your RODI or the barrel/plumbing to barrel is leaching it.

Edit: test the po4 not tds
