Who uses Fozdown?

I've used it to bring the PO4 down then maintain with GFO. Thinking just moving to a continuous drip and giving up on GFO.

My success with GFO has been marginal. Although it's not necessarily all the GFO's fault. Usually I have the greatest of intentions of swapping it out regularly, and keeping it up for 6-10 months religiously. Ya right. I'm good for the initial getting it set up, then usually 2-3 months down the road I remember and think I should change it, and probably another month goes by because I rationalize that I just got it going a month ago, it should be good for a little while longer.
So needless to say I can't say I've ever even had a noticeable change in my tank. Somehow I've gotten pink cotton candy algae in my tank and if left alone it gets to plague proportions. I may have to give Foz down a try.

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.
