cyano

[innate1]

I have been battling cyano for about two years. I've done 3 days of darkness, cut down feeding, increased flow, biopellets, chemiclean, gfo,gac, lmnop. All to no avail. My live rock looks like I covered it in velvet. It gets worse in the summer and I seem to get a little ahead in the winter months. So I bought a chiller. No real change. I'm at my wits end. I love zoa's and the cyano is invading my dragon eyes. Any help would be appreicated.

Well.......stupid question..

How's your lights?

I had a BAD cyano problem here recently. This is what I did:
1. Replaced the lights - it was time anyhow.
2. Started prodibio pro products.

I did those two things at the same time, so I'm not sure WHICH made the difference.

Oh and a couple waterchanges. Because I hardly do them anyhow.

Lights are 4 months old, I do a 15% water change weekly
