yeah i too am having trouble getting POH on mine down too...i made 50 or so frag plugs...which have been in the toilet for well over a month now...

i lost the colour chart fro my FW test kit...but when i test the RO water it is light green and when i test the plugs after sitting in the ro for about 6 hours the colour is blue...based on my SW kit i can only assume the PH is considerably higher...i will try the vinegar route to try and break things up a bit and speed the process..
