Hello, somehow in just 1/2 a day my Zoas have a strange red covering? No ideas what the heck this is, but this rock is solid Zoas and the red areas grew over my Zoas. Did not see these at feeding time yesterday. Please help.
just keep blowing them off until you get the cause in check. Probably elevated phosphates. Change a little water, run some carbon suck it out with an air line tube. Just take it slow.
