@Byron I have just done another water test, and my pH and GH have increased back to what they originally was. I haven’t added the rock back in. and my test the other week proved that the sand wasn’t causing the pH and GH to rise.
Could there be something else causing this ? or do you think a water change every couple of days for a week could solve the problem ?
I do not know if calcium or magnesium will penetrate objects like the substrate and leech out later. Perhaps another member will know.
Another possible is the source water may vary depending where it comes from.
