Running a Skimmerless tank

I know, I should read your whole thread Sheena ...
Have you tried changing your powerhead locations and siphon out the cyano daily ?

From what I've learned on Canreef, once cyano gets a foot-hold, the only good way to get rid of it is to siphon it out
It may start with low, or high, flow rates. Once you have it, increasing flow will probably make it worse as you are now 'feeding' it

After it's gone, increasing flow rates in the previously affected areas may reduce or stop it's return as you are stopping food from settling in that area
