Hi, I had a quick look myself as very much a learner on rock use in aquariums.

It seemed that it depended on where the rock was sourced from / made of but also mainly if there was organic matter in it? So perhaps old inland reef mined for aquarium use would be quite clean (once washed) and ok to use?

Dry rock is free of the organic matter.

It is calcium based, so if you cannot have the hardness in your tank raised any higher, i wouldn't use it, as it will raise the hardness of the water a lot. If its ok to have harder water, then you can use it.

Personally, I would not. I'm assuming by dry rock your referring to the base rock used in saltwater.

Some nice lace rock would work or as a cheaper option if you live in a region with natural stones just pick some out and boil them. Test first with the vinegar method to see if they will alter your water chemistry.

I have 150lbs of dry rock (base rock) in my 160g (84x18x24) african cichlid tank with 20 mbuna and 3 haps.
