Black cyanobacteria is a thing but I've not seen it lift in sheets like that.

Have you tested for phosphates?

no i havent

Sorry Byron but I have to disagree @Byron.
All my tanks have 4000K lighting and plants do extremely well.

I was told PAR is more important than color.

I personally use a 3000K LED lamp with a small number of 660nm red LEDs. Plants grow great with this light.

I have, it happens all the time when it photosynthesises. Oxygen bubbles build up under the film and cause it to lift off. It helps the stuff spread to new areas but also makes it easier to remove, sometimes.

Get a net under it and lift it out in a big sheet. Have a plastic container near the surface to put it into. Then bury it in the garden.

I've got to get a new phosphate test, if potassium doesn't help with my red cyano. Removing phosphates used to be quite helpful

I hit another group and got ideas, going to my own thread.... more questions than answers

 

[connorlindeman]

even more bubbles. Gonna try to peel it back today

 

[connorlindeman]

Just did 1 half of the tank. Peeled back super easily.

 

[connorlindeman]

There we go. Still some on the shells.

 

[Colin_T]

Take the shells out and hose them off. Gravel clean the sand.
