I need to clean my sand bed and do a water change, but is there anything else that I can do to help reduce my cynao problem? I dont know what caused it... The only real change was the addition of running carbon through a phosban 150 reactor. Would that have sucked out some stuff that would cause the cynao to bloom? Should I run phosban too?

What kind of carbon? Some carbon is washed with phosphoric acid, and leaches it back into your system. I use seachem matrix carbon. I have had a lot of luck with it. How is the water flow in your system. If it is in a few places try directing more flow to those areas. One good thing about cyano is that is grows quickly and if siphoned daily, it does help a little bit,to revmove alot of water quality problems.lol I know thats not what you want to hear. HTH Steve

always kidding
remove the sandbed and skim skim skim. 
my understanding about carbon is it is suppos to go in an area of low flow. carbon breaks down easy. forcing water thru it causes it to move in a tumbling effect thus friction and causing it to breakdown. and since carbon is an organic sustance as it breaks down it releases organics back into water. the best way to test this is to run your phosban reactor on a five gallon bucket of ro/di water test the po4 at start. run your reactor for 24 hours and test again. now as for your tank start running poly bio marine filter on it.cyano is when too much organics are present on the water. thus the reason why i removed my refuge from my system. cause my main tank never had it , but my fuge did.
The cyan has just found a place where it has the right enviromental parameters for it to grow. In this case probibly a flux of nitrogen coming from the sand bed. I would let it grow for a bit and then syphon it out. That way you are using it to export and it becomes a good thing. If the problem persists then other stepsshould be taken but that is all I would do for now.
