What kind of algae is this?

[biofish]

I’ve never seen this before in my tanks and it just started growing in my planted 55 gallon tank. It’s not spreading at an overly alarming rate but it’s still really gross. Looks like a plasma or slime. It’s only on the sand.

That's cyanobacteria, aka blue-green algae

I'm usually ok with algae but that looks sick... Like a bad sick, gross sick. I have no idea what type of anything that is!

No... That is no bga...
Bga is what's on the rock in my profile picture

100% Blue-green cyanobacteria.

Large water changes will help get rid of it. Spot remove it.

Look at it on the sand. That looks just like blue-green algae to me.

Guess a sniff check will be in order. Wish me luck

Seems too bright and too neon-like. It also looks thick and slimy. I have never seen bga like that if it is.
It looks weird

Thats one sure way

BGA is slimy and you can siphon it out in big sheets

Yes that's bga! But that's not what I see in the pics...

Good luck and don't kill yourself by doing that

I just had this stuff in both my 20 and my 40. Looked just like that.
