It sounds like cyano. A skimmer would be super beneficial. For a light timer, you can go to home depot, lowes, giant eagle and get a cheap light timer http://www.homedepot.com/webapp/wcs...angId=-1&catalogId=10053&productId=100652847.
You can buy hang on the back refugiums, but they are pricey. I would get a skimmer first, and probably increase the flow, and shorten the light on time.
