My tap water is absurdly soft, so I ordered this in hopes that it would raise my KH as my PH was very unstable. After putting a small handful in a filter bag it's been in hob for a few weeks now. It seems to be working well, my PH has been stable with no issues.
well, to be honest, didn't need that much but better to have more than not enough used it to assist in my city aquarium water so far has done exactly what I wanted a hight ph mine was in low 6 know 7.2 well done and thanks they knew exactly how to fix my problem took about a week and added just a little bit to fix it thanks again
Perfect! No complaints
