Arrgghhhh Methyline Blue

[Hally]

Please help me try to fix a problem I have.... I had to put a treatment in my tank but I never removed any of my prize red sandstone type rocks etc & now theyre a horrible colour what can I do ... Help Appreciated

2 cap fulls of bleach in a 5gl bucket filled w/water,. drop a power head and let it run,. rinse it off after a day or 5, however long it takes to get clean.
the bleach will not be toxic if you let the rocks sit outside water for a day or 2,. clorax evaporates in air,. but cleans rocks great

I thank you ..... I wanted my rocks back to normal, they look so horrible... but that sounds like an easy fix .... Thanks Again
