I have some marine snow and a syringe so where would i need to squirt the marine snow? would i need to do it over the whole rock or it has this yellow thing on the rock is that the core do i need to feed it. My salinity was reel high and killed my chromis, so am going to get my hydromitor calibrated at LFS. i got the fish and polyps at same time and they dont look so hot either. So when feeding what should i do?
