A week or so ago I was cleaning my turtle's 55 gallon tank, this includes removing the rocks (on the bottom of the tank) from the setup to rinse off. I purchased medium sized rocks because small gravel+turtle=bad. I also had the intention of being able to re-use the rocks, becuase I am on a budget.
When I clean the tank I usually just throw the rocks in a colander and set them to the side for later rinsing. My sister's cat, Gus, took a long piss on the rocks, and so now they smell like pee. The turtles don't have any rocks in their aquarium (which I know isn't okay). Is there anyway I can safely clean the rocks? Should I just buy new?
