im new and would like to know how to get rid of this red alge stuff all over my live sand.

your phosphates and silicates are most likely high, these help the red cyano grow all over your tank. Are you using RO water or just tap water? Switch to RO immediately and get a phosphate sponge (seachem). When you get the ro water do a water change and then for the rest of the time use only ro to top off and when you change. good luck it will be ok

If the tank set up is relatively new it is common. It is an indicator of a few things:

Overfeeding possibly.
Low flow to the area with the cyano.
Phosphates are too high.

Cut back on feedings by 1/2, let the skimmer run "wet" for a little while and use Kalkwasser for your make up water. It is not actually an algae but a bacteria bloom. It has to run its course a little, just be patient.

yes i have a ro maker and just did a water change yesterday. i had the tank for 3 weeks, up and running. i bought from my inlaws. they had it up for 2 years. we just moved it to my house. i added a couple of damsels, blenny, astrea snails, eel, cerith snails, hatian pink tip anemone, clown. i use kalk and dont feed but one a day. the red stuff is all over my sand, down under were the glass is too.

Get some powerheads, you most likely don't have enough flow in your tank. Point them to the sand enough to stir it around, but not enough to create a sandstorm. What bleueau87 and kolokefalo said, was spot on, do what they suggested.

If the algae is growing fast & like a red velvet blanket, your tank is suffering from "Old Tank Syndrome" especially if you used the water that your in-laws had. You need to address the causes of the problem - test for phosphates & nitrates. The phosphate sponge will help eliminate the algae but doesn't address the cause. You can also lower the phosphate & nitrate levels by following this water change method: An Instant Nitrate Reduction Method - A Multiple Step Water Change Procedure Just be sure the temperature & salinity of the water are the same as that of your tank. Use the RO/DI water. Also check the composition of your salt or carbon if you're using that to see if it is high in phosphates. You don't really need to feed everyday.
If you can, give us some more details about your tank like lighting, filters, etc......Also test the water & give us those results as well.
If the algae is hard & brittle you have coralline algae which is a good thing.

yeah my buddy told me today that is was a good kind of alge.
