I think I am starting to get some red cyano bacteria forming on the sand. I physically removed it (as it kind of sticks the sand together to for a red skin), but after about 10 hours, it comes back. What causes this? I assume this is not a good thing. I started getting this after feeding mysis more often. Maybe I am overfeeding.

As well, I have noticed that I have quite a bit of red stuff growing a couple cm under the sand along the front side of the glass. Should I dig it up and try to remove it, or should I just leave it.

Thanks
