Nice adds Mike and Jay!
Cheng, you just got a 180 and you want to upgrade already?!
Sorry for your troubles Greg, equipment failures are the worst.
Cyano seems to plague everyone at some time or another. If a tank is fairly new, I think it just comes with the territory. You have a whole lot of balancing acts going on. In terms of bacteria. Just when your biological filtration/good bacteria is getting good, we mess it up by adding 2 new corals and a fish, and then your tank balances out again to the new bio-load, and then you add something else. Cyano is a bacteria and when their is an imbalance in the tank you give it a chance to take hold. Along with the usual suspects: over feeding, lack of flow, and bad lighting etc.
Then you have a more mature system and things are coasting along nicely, and then suddenly it shows up. There are various reasons for this, and they usually fall under the category of a build up of phosphates or nitrates or adding something or even taking something away, Some sort of change in general.
All of this to say, that once you cut back on your feeding, get better flow through the tank, your photo period is good, and you dont have mass amounts of detritus building up somewhere, and you have the right skimmer if you are running bio-pellets etc. and you still have cyano, its time to fight the bacteria with some more bacteria. Dosing beneficial nitrifying bacteria to the system to regain balance has worked for me on 3 occasions. I highly suggest using Microbe Lift 'special blend'. It can be found at Petco. I also know there has been a few folks that have had good success with chemi clean, but i have no experience with it. Okay, I'm getting off my soapbox now....:blah:
