Got some sps corals last night and placed them in the tank with some reef glue and one of them was already a little white at the base but this morning they all looked alot whiter, not sure what it could be because i have a other sps next to it like raptors claw and birdsnest and they look extremely healthy but these corals were in direct flow, ive heard about some pests that are really dangerous to sps corals and are almost impossible to get rid of not sure tho since everything else is really healthy, i havent done a full water test tho so i'll probably do one soon any suggestions?
