grey rocks with white stripes

[duckweed]

I read and heard that these grey rocks with white stripes will steadily increase the pH of the water. Any solution to that? Or any fauna is suitable for high pH? Finally got my DC working!

ups!
can anyone help confirm my query?
will the rocks increase or lower pH?
thanks!

Maybe you can post pictures of your rocks. If your rock is those granite. If doesn't affect PH

Hi duckweed, the rocks you have are granite rocks - they wouldn't affect your pH. Hope this helps
