Hi All, I have a cichlid tank that is doing really well, I'm really pleased I switched to cichlids probably a couple of months ago and while the fish seem to be thriving I do have one small niggle, I have coral rocks in the tank and when new they were a bright white colour and gave me a display I was really pleased with, as well as my routine water changes every couple of weeks, I've removed the rocks twice now to give them a good clean with a jet wash, while this brings them up pretty well they have never been as bright a white as when new, so if when I do it next I were to soak them in a bleach and water solution I reckon this could restore them to as new condition, if I did what sort of dilution would I be safe using, obviously the stronger the solution the cleaner they will come but then I wonder how much rinsing I'd need to do before they were safe to re use in the tank, I'm thinking maybe the only really safe option would be to buy a new selection of rocks then I could have one lot in the tank and the other lot I could bleach then leave them soaking for a couple of weeks or more and then do the same in reverse the next time, it would save me a chunk of cash if I could just rinse a re use but the tank is doing so well I'm nervous of upsetting the water parameters, so anyone any opinions?
