I was thinking of possibly using them if they won't change the pH. I haven't tried a vinager test yet (I don't have any but could buy some ). The pH of my tanks naturally run 6.8-7.2. I haven't checked the gH lately but last time it was 3 (if I remember right). Anyone know if marble will affect the ph?? Steph I used to be Snow White, but I drifted. ~ Mae West

It could change your water's hardness and pH. Another concern is what you are going to have in the tank. If you are going to house Rift fish, and no plants, then the chips might look good. However the chips are too large for plants to anchor in. The large chips leave large gaps for fish and food waste to accumulate in between and rot. Additionally, fish tend to be more comfortable with darker backgrounds and more natural looking substrates. White chips could cause stress and keep many in seclusion, hiding under plants or in caves during the time the lights were on.

I am planning on putting a couple of larger central american cichlids in the tank so no plants anyway but I definately don't want to change the water chemistry.
