How can this happen

[Esquire805]

So for the longest tim mu phosphorus/ phosphate has been off the charts. I use a hanna checker ulr ane ir blinks 200 but since I have been usinging phosphate e, it is now at 28ppm. My tank grew coraline algae om the walls fish are not dead, clean up crew is alive. I should anything above 6ppm was killer, please explain.

Please research. Phosphate feeds algae, and excessive amounts can impact corals and calcification, not fish or snails.

That number is ppb and needs to be converted from phosphorus to phosphates. IIRC, 200ppb converts to like .6 ppm of phosphates. No way you have 28ppm of phosphates. Neither Hanna checker can read that high.

Corals are alive I got two acros to test the water they were brown green but starting to color up as phosphate goes down

Oooh it was 92ppb which was 0.28
