Salt Water Coral

I have dark red " something" growing on my coral. Once a week I do a partial water change &, with a soft brush get most of the red off. By the next week it is back, sometimes worse. I have tested the water. Everthing is fine.

What is this "red stuff?" Is it dangerous ? How do I get rid of it ?

Probably gonna need a picture for proper ID.

 

sounds like cyno bacteria to me Salty fresh it can choke corals , depriving them of light and nutrients

check the sticky on the algae forum for positive ID ( Ultimate nuisance algae thread) or if you can post a picture and that will help get a positive ID for you

cyno if thats what it is can be beaten by increased water flow, as it prefers still areas of the tank coupled with reduction on nutrients - your test kits may say everything is OK but the cyno is using them up as quickly as they are generated so nothing appears on your test

That's what I thought initially too. You are going to need to get your parameters in order, cut back on feedings, increase flow, decrease lighting. (If that's the case).

 

Thanks for all your suggestions. I'll begin today & let you know how it goes. I love this site because of the help & suggestions you get from others.
