I picked up some seiryu rock at the pet shop. I didn't realize till i cleaned it with vinegar that it reacted. When it fizzed with vinegar I pulled it out of my tank. Which had been holding at 7.8 with one piece.
I added driftwood about the same time and my PH started slowly falling to 7.7 in 24 hours. I put the seiryu back in more this time as I have it all clean. The PH has stopped falling and is slowing moving back up
Does anyone know how high seiryu will push the PH ? If its only pushes to 7.8, it may actually help my PH be stable.
I also hate to toss it as I like the look. It has white streaks / specks I'm guessing are calcium carbonate.
