What's an acid test? Run some acid on top of the rock and see how it reacts? Would muratic work or something stronger?

I have some slabs of slate and flat shards of limestone and other various rocks that I want to make into rock caves and structure in my African tank. Are there any types I should not use in a tank, or any rocks ok to use?

Once I am able to get into saltwater I will for sure go into canreef, thanks for the heads up

New to here, thought I'd say hello. I've got a 55 gallon with African cichlids including 1 female venestus, looking for a male for her, 2 special 44, 1 denasomi, 1 kenyi, 1 electric yellow and 2 female ob. Also have a small 20 gallon with a few what I'm assuming are juvenile peacocks and a 55 gallon hex tank as a community tank with barbs, tetras, guppies, and frogs. Hoping to get some info and maybe some new fish and a bigger setup, and eventually get into saltwater tanks.
