How to get rid of these red stuff?

Try to siphon out what you can and do a few water changes. It should help out tremendously.

I don't know of anything that eats it.

Get some sand sifting snails or a diamond goby. My goby won't eat the cyano, but does keep the sand clean of debris. I've got cyano on my rocks and I've been blowing it off and syphoning it out. I have also changed the flow in my tank and this seems to be helping. You may not be able to add more flow, but you can change it around to avoid "dead" spots.

Some claim blue and red Hermit Crabs will eat it, however, all crabs are selective eaters and will eat what they want, when they want...

I suggest purchasing some Nassarius snails as well. They are sand sifters. They will not eat the cyano but they will eat the left over food particles, etc. as well as stir up the top layer of your sand bed.
