Hello, i bought a jar of pink acidifying pH granules over a year ago and they worked great. They were some kind of buffer and they brought my pH to where it should be and KEPT it there. I've since run out and now i can't find them in any store anymore. I'm now using pH DOWN from Aquarium Pharmaceuticals but it's expensive and two days after i put it in my pH has bounced back (to the alkaline side) to where it was originally. Does anyone know what those pink crystals were and where i can get them?
thanks!
jim
