I'm gonna put this on the ac forum because I'm sure some of u use the coral rocks with ur ac's they have algae growth on the rocks I've tried the scraper/algae removal stuff in the bottle and nothing anything that I can maybe soak them in without harming my fish a product to buy something?

I don't use anything. For flat pieces, I just turn them over. The algae dies on the underside and I have clean white coral rock facing up. With larger odd-shaped pieces, I remove them and place them outside in the sun. The algae dies off pretty quickly. Then, a quick dip in diluted bleach and a good rinsing makes them ready for placement back in the tank once the replacement piece needs cleaning.
