Red slime

[Lanieverret]

Have this gelatinous red slime in my tank. I have checked my water and all is good. Fish and corals are good but not sure what this is.

Cyanobacteria, check your phosphates and increase flow.

+1 cyano, you can also siphon out what you can, check nitrates, increase flow and watch how much you are feeding, some people decrease light time but remember cyano is a bacteria also one of the earliest living creatures known to man actually. Good luck!
