Local water high phosphates

So, my local water seems full of phosphate (5+). I just switched over from PPS pro to EI dosing regime, should I still add the KH2PO4? Seems redundant....I'm using a phos absorber in another tank after a huge algae outbreak/cloudy water/ deaths. Had thought to put that in this tank too, but then why dose it on top of that? Thoughts?

Skip the KH2PO4 and test the phosphates in the tank right before a water change. If there is still a positive test (no matter how low) then the plants are getting enough phosphorus from the water change.

If the plants have used up all the phosphorus you might think about a low dose just once a week, a couple of days before the water change just so the plants do not run out in those last few days.

Got it. Thanks for your reply; my computer crashed or I would've responded sooner. I've spent days reformatting/ reloading/ hunting for things.
