Red Algae

[GreenTerror7]

Should I turn my spray jets at the back wall?

I've not heard if red Cyanobacteria but it probably does exist. Be warned, if it is then get rid of it, fast, it's a mango fish killer! Dose H2O2 to kill it, won't have any negative affects on fish unless you overdose it, also adds O2 to the water.

How much h202 should I put in a 135? I'm trying to get rid of it ASAP

I find that it is often caused by a shift in ones lighting spectrum. Replace older tubes etc, or try different lights. LED's solved a massive cyano outbreak that I had in one of my tanks a few yrs back.

I'm not sure what type of light I have in it at the moment since it came with the tank when I bought it, all I know is its a 48" fluorescent t8 bulb. I will change it though, what should I change it to? I don't want to spend hundreds of dollars in LEDs btw

Your old T8 light is most likely the cause of your cyanobacteria outbreak.



It's amazing what one can find via google.

Good luck.

Beyond cyanobacteria, there is also true red algae.
If it feels slimy, it is normally cyanobacteria, but if it feels gritty it is probably true red algae.
Either way, light and mineral content are the determining factor as far as what color/species of algae it is.
I have a tank that gets indirect sunlight for part of the day, and rocks and wood are covered in an orange tinted true algae. In photographs it appears brown, but to the eye (spending of light and time of day), it is often reddish.
Fry constantly graze on it, and I have found if I put fry in that tank, they tend to grow very well.


At the moment I have a group of Coptodon zillii in the tank, that graze on it.
