i DIDN'T KNOW THIS

Through All The Reading I Have Done I Wasn't Aware That Cyanobacteria Comes In Green As Well. I Just Learned This Through A Thread. Anyone Got Pics Of Green Cyano? I Thought It Was Only Red.

 

It comes in all sorts of colors including red, green, black, blue-green (hence the name blue-green algae).

Here's some green cyano

nemo79 you can just about always tell cyano by two things -if its green its brilliant green and it always seems to contain lots of bubbles in it-

 

Oh Great. I Noticed A Small Patch Of Dark Dark Green Algae On My Back Glass And It Kinda Has A Few Bubbles. The Weird Thing Is I Have An Mj 1200 Directly Blowing In The Back. I Hate Algae And Definitly Don't Want This Type.

 

All of us have cyanobacteria in our tanks. There's nothing we can do about it. They are invisible and pretty much harmless.

UNLESS.......you have a population explosion. Then it's downright ugly and if it gets bad enough, it can smother your corals.

One method people use to keep cyanobacteria in check is good water movement. A bacteria's body is hydrophobic which makes it easily skimmable. People with good water movement and a good skimmer have less problems with overpopulation explosions.

However, once you have enough for it to be visible, the best way to remove it is to siphon it out before your next waterchange. The second best way is to repeatedly keep forcing it into the water column for your skimmer to grab. Either one of these methods will take the phosphates that they absorbed right out of the tank with them.

There's a product called red slime remover which will kill cyanobacteria. However, that does not remove the phosphates from the system. Once you kill the cyano, the absorbed phosphate becomes bioavailable for any other nuisance algaes that you might have in your tank. You could possibly make a small problem worse.

The key to cyano control if figuring out what's going on in your tank that is causing excess nitrates or phosphates (or both). For instance, it could be overfeeding, underskimming, overstocking your bioload, etc.

 

Well I have a powerhead directed to the surface, one to the front and one to the back wall plus my filter for flow.This is a total of 781 gph that's 14.2 x turnover in my tank. I only feed once a day and not alot, my lights are only on for 11hrs, I do water changes regularly with instant ocean salt, I use ro water and I clean my filter media once a week.
I hadn't did a water change in a month and my tank looked awesome, no algae problems, I cleaned my glass with the magnet 1 every 2 weeks. As soon as I did a water change I noticed green algae growing on my glass immediatly. Now the algae I think is cyano had been growing for a while but didn't have a slime or bubbles until the other day. How do I syphon out the algae on the back wall on the glass...I don't think I could get my syphon to fit? I don't want to use any chemicals, rather manual removal. Could I wipe it with a cloth to remove it? Not scrub it and release it into the water but use a brand new j cloth, wipe, rinse and repeat? it is a patch a little bigger than 4 quarters. and it is the only patch.
