I collect a few stones each time i go fishing to put in the tank. Whats the best way to clean them. I will not boil them due to the grenade effect. I heard of using bleach,vinegar, or ph down. Ideas???
a 2:1 (water: bleach) solution is a perfectly viable method... chlorine evaporates in about 36 hours or so. Just leave the rocks out for 3 days and your good to go...alternatively soak them in dechlor and they're good right away.
Our service company does about 40 tanks a day and this is exactly what they do.
