He threw it out as soon as he drove out of your neighborhood! :lol: :mrgreen:
Well not a 100% however I never have had brown algae and cyno problems until after the rock was in. I tried a phosphate test but with all the brown algae it comes out 0. The rock was getting covered in thick layers of the brown stuff. When I would blow it off with a power head it would come off in sheets. Thats the only rock this would happen to. The fiji stuff I have didnt get the brown crude. So to me the rock must have been giving something off that the algae likes and two the rock isnt porous enough if it cant even hold on to algae that is growing on it. So I pulled it better safe now then screwed later when I add corals.That sux Ted.
Are you 100% sure the rocks leaching stuff?
