Cyano...chem additives?

[Brad]

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.

Chemi-Clean worked really well for me but this just kills the cyno doesnt keep it from coming back from my expierence.

I used Chemi-Clean also. With great results the next day or two. but then about 2 weeks later it came back. then i just added a little more and then did a huge water change. and wa-la. it was gone

in the past i used phosguard and it worked no problem but its been gettin to me latley my lights are new so its not that but a long day might be part of it 12-13h of light per day one tank has a little nitrate problem and the other is great i feed mostly frozen krill and shrimp in one and mysis shrimp in the other
i have a 3rd tank was a 20g but moved up to a 50g never a spot of red 1 or 2 hours less light per day but a lot less food goes in thier just a redspotted hermit to feed even though he makes a mess
makes me believe i over feed to much but thier so dang hungry pluss the wife beakin they want more dont starve them dont help

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.
