Hello reefers. Today I bring something I haven’t seen in my aquarium I reset this tank three months ago dry rock and dry sand currently I have 0.08 po4 and no3 at 6.8 started off with diatoms then this stringy algae came at the 3 month mark no idea what it is. Any help would be appreciated. You can also see that the rocks look a very dark brown. This is a fairly high flow tank with high intensity lighting. Makes me think it’s gha but I’m not sure.
