I have some old rocks I pulled out when was dealing with bad algae and pest issue. They’ve been sitting in a bucket in my back porch for months. How can use some these pieces again. Last time I did this I soaked them in bleach then let them dry in the sun, then rodi rinse, then into a dark container with a lower head for a few weeks. Can anyone give me specifics on the steps or If I only want a small rock or two is it better to just go to the lfs? Lol
