Red Cyano Bacteria

[Tigger]

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

There are as many reasons given for cyano as there are cures. A number of purists would throw up their hands in horror, but when I get it, I use Chemipure. It gets rid of it in 48 hours or less, and has no bad effects.

I would be inclined not to worry about that. It is common, and no cause for worry. If you look at Shimek's sandbed FAQ, he talks about that.

I'm starting to get a bit of it too. That's why I'm looking for conches.

I have 2 fighting conch (got them from sea care) and they make short work of Cyno, about 1/3 of my sand bed was solid cyno a 10 days ago now less than 10% off the cyno is left..

I have found that heavy feeding alond with reduced skimmer efficiency (I for got to clean it one week ) and my conches taking a week long nap are the major contributers to cyno in my tank. I also contribute this latest (and my worse) outbreak to some new rock I added to the tank (about 26lbs) I suspect that it might have brought some phosphates along with it as I got a brown/gold algae out break with in days after adding it and then that turned into the cyno..

Just my observations

I also have some brown golden algea forming on the live rocks.

I've fought long and hard with this nuisance algae as well. I've just recently taken control. I believe the addition of a skimmer to the system was the greatest benefit but I've also began to use "Phosguard", by SeaChem. I "slow-flow" all make-up and replacement water through a homemade "cylinder" in addition to GAC cartridges. (the poor mans RO/DI). I haven't tested for phosphates or silicates but with no cyano. visible, I believe it's working.
