Increase sensitivity of API phosphate test kit

Unfortunately I bought this kit and I see it is not very sensitive at low levels of phosphate.. does anybody have a solution to increase the sensitivity for low levels?

Yes imo I would Throw it away or sell it and get a Hanna ulr phosphate tester

Thanks for the recommendation, I decided to buy the Red Sea pro phosphate kit which has been easy to read, and has revealed that I have no PO4 in my DT and 0.06 ppm in my QT. Glad I have more accurate numbers to work with instead of the big jump in the API test kit

Try to get your po4 up in the DT as it could lead to cyano and or Dino’s. Zero is never good for your phosphate or nitrate readings . Recipe for disaster imo .
