Aquarium Advice Apprentice
recently i went to the beach, and since it had been eroding, they dredged up a bunch of sand, and with that sand came a ton of old gray colored lava-type rocks. i've looked all over, but can't find anything aboutr treating them, so i put them in a 10% bleach solution for now. They're really cool rocks, and they're full of tunnels and arches. If anyone knows what i should do with them after the bleach i'd really appreciate it! tyg
