i soaked some of my old rocks and plants becuse they had algae and crap dryed on it...soaked it for about a day then soaked in some declor water for about 2 or so hrs..... i was told that after the rocks dry out the bleach disappears.....is this so or is their a hazard of some ammonia leaching off the rocks and plants when i put them in my tank. Im thinkin that once the rock drys and i put it in the tank the levels if any that might leach off would be taken care of from the bacteria i just wanna make sure i'm not adding a ton of ammonia/chlorine into my tank
