220 red algae

220 gallon setup for many years. Running ration pro 4. Red algae is everywhere. Fish are fine corals not looking good. Any ideas. Thanks

If it’s red turf algae, throw in a handful of urchins and that’ll be all she wrote

I had the same problem. I used Mexican turbo snails. Worked very well.

Of course you also need to address the excess of nutrients in your water feeding the algae.

What kind of red algae? Is it a slime covering, or is it a hair alga of some type?

Sorry, I did mean to write it - it was a red hair algae in my case.

Here is a picture.

Need pictures from kac01...
It could be an algae of sorts or it could be cyanobacteria..
Treatment methods are different..

It just blows off rock if you put water flow on it. Comes back within a couple days. There is lots of flow in tank but doesn't keep it away.

Sounds like cyanobacteria.. (not an algae)
I'd suggest you google search images to see if that matches what you have..
Then a simple google search will yield THOUSANDS of results on how to treat it..

I recommend siphoning out as much as you can with your next water change then turn the lights off in the tank for 3 days.. Then siphon out anything left after that time and repeat every couple weeks until its gone..
Or you can try the chemical route of using products like Red Slime Remover or Chemiclean.. Follow the directions EXACTLY and note that there are a few individuals who claim it had negative effects on their tank causing coral loss/fish loss,etc.. But realize that most who use it do not have that problem at all..

Sometimes, nutrient control will fix cyanobacteria issues. You could consider cutting back on feeding, or using GFO, or carbon dosing. Carbon dosing would include something like NOPOx, vinegar, or vodka. Details are available, if you are interested and need some.

Has the skimmer been cleaned and tuned lately? Sometimes, better skimming helps.

Spending a few minutes every few days or so siphoning out as much cyanobacteria as is easy to get might help. Some fresh carbon might help the animals look better, as it might be able to remove toxins (if any) that the cyanobacteria are releasing.
