Thanks Mitch I'll look it up.

I was using just Fozdown for a while but found I couldn't get the dosing right using it just on it's own. All the problems I associate with GFO (namely cyanobacteria) went away when I was just using Fozdown, but I've never had to scrape my glass with a razor as often as I did when that was my only method of Phosphate control.

I've now switched to a GFO that's encapsulated in a polymer bead, which seems to mitigate a lot of the problems that come with GFO use, and use Fozdown supplementally if I find the rate of film algae growth gets to the point where I need to wipe the glass daily.
