This is bga/cyano algae, yes?

[neoh]

Just looking for verification that this is infact BGA so I can treat it. It latches on to my blyxa, crypts and gracilis, but stays away from my java and pogostemon.

It's really starting to thwart growth, and I would like to nip it in the butt, but I just need to confirm that this is the algae I'm going to be fighting!

Thanks.

Bta is usually darker. How about fuzz algae. Check out this guide

Agreed. It does not look like BGA to me as well.

nope not a Cynobacteria

My potassium levels were through the roof, and the timer for my co2 somehow went haywire and left it on for three days, and poof. Everything is covered in hair algae.

Changed my dosing regime to compensate! Thanks for your help!

Not sure what you are using to measure potassium, nor what you define as "through the roof."

In general, potassium levels can be quite high without any apparent harm to livestock.

As others said, not BGA, but hair. BGA is an unmistakable blue-green film.

Not sure what your dosing method is, but that's not the problem. Too much light or too little CO2.

Up the CO2 as much as your fish will allow, and then throttle your lights via photoperiod or intensity. That hair algae will clear up in no time at all.

It actually could be cyanobacteria, just not the type people are used to seeing. Some "algaes" can only be distinguished from one another by looking at their cell structures through a microscope.

Smell it, if your nostrils dont fall off, its not Cyano...
