So im in the process of scaping my african cichlid tank, i could only find flagstone at my local home depot(for making caves because its thin and light) and i was just wondering if it was safe.

put a couple of drop of some white vinegar on rock if it fizzes its no good

Go to a landscape company and look at some slate, lots cheaper than flagstone and known to be aquarium safe.

The vinegar test doesn't work because it indicates limestone, which is bad for soft water tanks, but good for african tanks.
