This is a good read. There are quite a few reasons for cyano and as you go through the article, check with your system what you know to be "OK". Light's for example, if you have brand new bulbs, you should be able to rule that out. Good luck and hang in there, I hated having Cyano.

Great Link
Do you have an overflow on your tank or do you skim from below the surface. I have the same problem with my 45 as the skimmer wont pick up surface nutrients and I get the same thing. After reading this article I'm going to start pre rinsing my frozen food and stop using flake for a while.

You need more flow aim 1 high to chop up the surface of the water

Like you said ...you are using a skimmer rated for a 125g tank on a 150g, and also it is a skimmer with a less than stellar reputation. I also agree with Murminator, try aiming a power head towards the surface.

MO flo
I battled cyano forever... I found getting a larger skimmer mine is "rated" for 450 gal on a 180, and increasing the flow in the tank beyond what I thought was reasonable. I also started rinsing my food 5-6 times beforer I feed it, and running a phosban reactor to lessen the available PO4 in the water collumn. I also gave up on having sand in the tank and went BB (after about a year of frustration)

i jsut beat a small uprising of cyno.. i did a partial black and added a nano korialia for flow and in 5 days there is bareley any trace. some spots it was 2inches around and now is barely noticable. i also have move aPH to cut the surface water.
