I'm having problems with my po4 it's at .11ppm on the hanna ulr checker I'm running chemipure elite and phosguard and it hasnt went down any at all. I notice some of my acros and digi are starting to stn
 
I agree with emde, that won't kill your coral. I would look at other reasons for the STN. Like unstable alkalinity or maybe over dosing NoPox or vinegar to keep nutrients down. Possibly water contamination
 
Perhaps the media has been exhausted and needs replacing?

Fwiw 0.11 alone shouldn’t cause stn.
Can you post your other parameters, light, flow and any changes to your tank?
Ya I'll post my parameters when I get home from work today. I just bought the frag from RAP chicago and been in the tank and starting to stn. For my flow i have a icecap 1k gyre and lights I'm using AI prime with the AB+ spectrum
 
I had high phosphate issue too. Although it hasn’t lowered < .05, but I can see drop in the number. I’m performing weekly 10-15% water change, replaced phosgaurd with phosban. At least for me, phosgaurd did not perform with their recommended dose. I’m still using Chemipure elite. In addition to this, I’m doing 5ml daily vinegar dosing.

FYI, I’ve a 40g reef tank. It’s only 6-7months old.
 
Ever since battling dinos with the help of this forum, I now keep my PO4 between 0.1 and 0.2 by dosing with Neophos. My nitrates run between 5 and 10 ppm. All of my corals are thriving and coloration is great. My Alkalinity is between 7.5 and 9.0 dkH

Ok thanks I'll try to switch to phosbond instead with the chemipure
