Ok, three things are required for algae; Light, fertilizer in the form of phosphates and nitrates, and Carbon Dioxide
You have to eliminate all three to be free of this nasty stuff. Red slime is not as hard to get rid of as the green stuff. you can siphon it off daily and eventually it will disappear. It seems common in new tanks to first have brown diatoms, then red slime and unfortunately, frequently green algae.
You may need to add an airstone to your tank, which helps oxygenate it, which the algae doesnt like(wierd, huh?) make sure your lights are not old and the wavelength has changed-they need replacing every 9 months to a year max. Make sure you are not getting direct sunlight from outside on your tank as well.
Have you checked your phosphate and nitrate levels?
Phosphate should be 0 and nitrate below 10 to control the algae. I had to add a phosban reactor to my tank, which helped some. A refugium works because the plants in the refugium soak up all the nitrates and phosphates in the water. Right now, you will need to crop the algae daily and get as much as you can off your rocks, while perhaps adding phosban, a denitrator, even a refugium, make sure not to feed too much and shorten your light cycle.
The coraline will come back, if you lose some of it. Iwouldnt worry abuot that cause you cant see it now anyway with algae all over it!
Agreed. The only thing I'm wondering.. is your tank an open top or a canopy? Although open tops will lose a lot more water due to evap. It will help a ton with oxygenating the water. This along with what Granny stated above should help rid of the problem
