More like the test methods used, either error on your part or the test kit is off by 5X.
I'd say the latter.
1 tsp to my 180 should add 5ppm extra PO4.
I dose this amount 2-3x a week.
Run a test against the known standard for the test kit if you wish, see the sticky at the start of this subform for more info.
