Cleaning Rocks And Corel

[Avinitlarge]

I am giving my tank a good cleaning. Ive cleaned all of the plastic and resin ornaments with bleach and the have come up good. I have 2 pieces of corel and 2 pieces of rock that I need to clean, I dont fancy using bleach as I imagine they are porus. I have scrubbed them and boiled them but the algae wont shift. Any suggestions??

Usually just a good soak and scrubbing in hot water will work with rocks, although you can boil them if you wish (just let them cool off). Is the coral for the community tank in your profile? I've heard it's not good to add coral to freshwater tanks unless you're trying to raise the Ph...

i would, normally, avoid this. especially in a mature tank. as it removes what makes the tank "mature".
