Cyano...chem additives?

I have been quietly fighting cyano for months now. Every week, I vacuum it off the sand and wherever else it grows...but it always returns.

Things I have under control:

Phosphate: I had barely measurable phosphate, but used some Rowa-phos. Now I can't detect anything.
RO/DI water:
Cut back on feeding: Usually one small feeding every 2 days!
Nitrate: Have never been able to detect any nitrate in the system
Skimmer: Maybe not the best skimmer in the world, but I have to clean it out every week...
Kalk: Dosed with meter 24/7. CA/Alk levels very stable.

Lighting: My MH is over 1 year old. My next step is to replace it and see what happens.

So I'm nearly all the way to chemical additives of some kind. Has anyone successfully used a chemical additive to beat cyano? I've never added anykind of chemical to my system and it worries me....but I'm almost out of options.

I had a really bad Cyano problem a while back. I used Seachem's De-Nitrate. It worked wonders.

I have used Chemi-Clean with great success. As mentioned, finding the source of the problem is the key. Perhaps adding more flow would help.
