Phosphate e doing opposite it’s supposed to?

[Reefing.with.Rich]

Wanted to drop my phosphates from 0.11 down some so I got some phosphate e and upon the first dose I tested a couple hours later and it went from 0.11 to 0.15
Tested today and it’s now 0.14
Bad batch?
Not doing it right?

I have been dosing it daily for months and it works well.

I’m so confused as to how it made my phosphates go up
I’m going to dose it again tonight and see if it goes up again
Thanks

I'll go with testing error. Don't over do it by trying to correct the dose. Just keep at it slow and steady.

Not sure this warrants an emergency tag but......what type of tester are you using?

Not sure how often the Hanna checkers are wrong but my reading have been pretty consistent
Always that chance though I guess
Def plan to dose again tonight and see how it goes
Thanks

By testing error I am not saying that you did the test wrong. All test have an accuracy range even when you do everything perfectly.

I can say with confidence that your phosphate e is not increasing your po4. Zero chance of that.

Keep us updated.

I removed the emergency tag.

Which checker?

The HI713 claims +/- 0.04 ppm, so the results can range quite a bit and still be actually unchanged.
