Help Got too much Red Slime

Can anyone in here show me the best way to get rid of Red Slime algae? I did a big water change but it came back after 2 days. I'ts all over my sand beds and my live rocks.
Thanks,
Tony

I tried many things, as many things can be factors in it's growth. Do you have excess nutrients in the water? If so, you aren't ever going to get rid of it. For me, what finally got rid of it was increasing the flow in my tank. I don't have it at all in my display tank any more, but it still grows in my low-flow refugium a little big. So, simply put, beyond the generic advice for getting rid of all nuicance algaes (getting rid of excess nutrients), up-ing you current is the best bet. They also sell a product that kills it. It comes in a little bottle with powder in it, don't remember the name of it now. I'm sure you can search online and find what it is called. Anyway, I used that with mixed results, and had no negative effects on my tank. But, BIG caution, as always, on using chemicals in the tank.
Oh, and if you just set up the tank, you may just have to wait it out. Going through a period of slime algae is pretty normal, and it will eventually go away on it's own (not that I'd blame you for trying to get rid of it ASAP)
 
I just went through this battle. I tried lots of stuff in succession in order to find the cause. Eventually I just resoted to all out war.
-Phosphate sponge
-reduced lighting period
-siphoning the sand bed
-chemi-cleen (the chemical krishj39 mentioned)
-more water flow
-rearrangment of rocks (OK probably didn't help but I'm listing what I did all in one weekend)
-two water changes (first 10% then another 20%)
all in all it's now gone.
I don't feed differently, never found anything dead, and I never had any phosphate registering at all. So I'm guessing it was just the normal tank break in thing to go through.
I feel your pain though, I was getting close to throwing in the towel. Full out war was the last resort. In retrospect I'm glad it worked, the tank looks better than ever.
Good luck. -Watch I'll go home to a full cyano breakout! :p

Hey again, I just noticed one of hookedonreefs comments. He said he siphoned his sand bed. If you have a deep sand bed and if you decide to do that, be really careful, disturbing the sand much at all will cause all sorts of bad stuff to be released into your water, making things worse, not better. If you siphon a DSB, make sure you are just picking up the algae on the surface.
