Thanks George. The flocs from Foz Down are not toxic at all.

There is many different grades of the active ingredient and companies make different concentrations. I use a high grade and have the concentration that it is very unlikely to be overdosed. It is strong enough to last an average reef tank of 90 gallons, 6 months to a year depending on fish/food load.

There is dosing instructions on my website at:

This product can remove Phosphate very quickly so you need to not overdo it and give the corals time to adapt to the lower Phosphate levels in your tank.

I personally use the "don't care and don't do anything option" as I view the flocs as completely inert. I clean the detritus out and do regular water changes but that's it as far as flocs go.

For those choosing to try to remove them I have 5 micron 4" filter socks available.
