Red Algae

[makairadiver]

I have a 72 Bow Front tank and it's been running for the last eight months. Just recently a red algae looking bloom has covered almost all my substrate. I have been siphoning it twice a week for the last two weeks and it doesn't seem to be improving any. Some people have told me that it is a bacteria bloom( red cyano bacteria) but I'm completely lost now. Please tell me how can I get rid of this noxious pest.Thanks for your advises.

There can be many causes for it but water changes and siphoning as much as possible will go along way to help. How is your lighting new or old? Do you use r/o water for all your water? How are your water readings mainly nitrates and phosphates?
