Hey guys

I was looking into an iwagumi setups and had some concern about the rocks selection. After reading reports of rocks raising Ph I figured I'd ask the experts two seemingly simple questions.

Are there rocks which don't affect ph and also, are there rocks which lower ph? I'd rather lower ph or keep it neutral seeing as my ph is already quite high.

lots of rock wont affect ph levels, but No rock will lower the ph. quarts and granite are two forms of rock that wont affect the water.
Please excuse the following but can you name names? For instance "Dragonstone" etc etc

What is your ph and how often do you change water

If you already have high ph water (i also am in the 7-8 range) tht means you probably have very hard water and its very difficult to change the ph with hard water. So youd probably be fine with something like sieryu stone
