Thanks D but regrettably I haven't done enough work in the tank lately.
You can see the cyano on the rocks if you look closely enough at the pics
Dammed thing is I had it beat for a very long time.
I started using MB7 awhile back as an experiment to deal with algae and, as has happened to some others, it brought on the cyano. So I quit using it a couple weeks ago and now will have to pay the price for it.
Curse you Walter
