Will pay someone with DIY experience in similar project to paint these 2 pieces.. I have 100 lbs of dead coral that I've had for a long time and it is bright white. I have to bleach every month as it is in a fish only system. I would like to paint purple but do not know what type of paint to use. I would like it to look like aquacultured live rock, it does brown out after about a month or so. Has anyone ever painted any base rock or white dry rock? Basically I would like to paint so I only have to brush algae off periodically and not bleach, if this was a reef tank I would just let coralline grow on it but that is not the case.
