Phosphates

[The Saltman]

Hello,

I just measured my fresh ro/di water in a holding brute storage can and it measured 0.01 for phosphates on the hanna. TDS out of the ro/di is 0. Could it be possible my brute is leaching phosphates into the water? I've had it setup holding water for 1 year.

It is possible but most probably the TDS meter is the one not being able to detect them, in any case 0.01 ppm should not be an issue.
