What? I usually just powerwash them with really hot water.

Sounds legit, same test and prep I do for all my large aquarium rocks.

Yeah they look like nice river rocks so I'm sure they're fine. As suggested, power wash with hot water and NO chemicals. Also splash some vinegar on them. If they fizz it'll mean they're calcium based and will raise pH. If they don't you're good to go!

Rocks to stay away from in aquaria are limestone and alabaster as they will "melt" releasing toxins into he water. Urs look a o.k. to use. Granites,river rocks, slate and most landscaping type rocks are all good to use.

They look like large river rocks that use all the time with no issue. Just clean well if youve used chemicals in the yard.

No, they look like they may be small explosives
