Dsr phosphate

Does anyone have experience with dsr phosphate? I have dosed 0,1 ml for 3 days now and have not seen any rise in phosphate yet (salifert kit).

Some phosphate gets bound to Rock and sand so keep going, until you see your first rise then stop for 24-48 hours and retest.

Not the best test kit for phosphate but will do.

Like @Uncle99 stated, phosphate will get bound to rock and sand. Also, it may take a few more days before it reaches saturation levels in the rock/substrate to be able to register on the salifert test. Do you access to a Hanna tester? What are your phosphates now?
