Treating dinos

[Jl330]

This is what I’m dealing with. Tank was an established tank that I purchased and added some new rock to.

It does not disappear into the column at night.

Nitrate and phosphate are reading 0 and I can’t get them up. I’ve been feeding twice a day and have a moderate load of fish and coral.

I bought microbacter7 but haven’t opened it yet. Can this help?

Any other suggestions?

Turned off my skimmer and fuge light

Might be cyano if it doesn't disappear at night....but I'll say it doesn't look good from the numbers.

If you can't get a picture of it under a microscope, at least perform the shake test. Dino's will move; cyano and other algae will not.

Take a sample of the algae and water in a vial or whatever, and shake the sample to smithereens. Then place the vial under your tank lights or in the sun for a while....see what happens..
