Hi after getting some advice I bleached my aquariums rocks, they were stained with methylene blue. Now I soaked them in a mixture of water & a cup of house hold bleach for 4 days, then I washed them in fresh water & heres the trick (I was told) I put them out in the sun for a few days no they look great, but I'm nervouse about putting them in my tank. Will it be ok now, does anyone know. Thanks in advance.
