Hi,

Patrick is correct that I use and produce Foz Down for Phosphate Removal. Thanks Patrick

IME Using Foz Down to bring down excessive Phosphates is the quickest, easiest and most economical method. If your phosphate is >2.5 then your rocks probably have bound up Phosphate as well. As you lower your Phosphate levels the rocks will release it back into the water. I would recommend using Foz Down to eliminate the Phosphate and then you can use your method of choice to keep it low.

If you have any questions I would be glad to answer them.

Cheers,
Tim

Don't forget though, if you use a chemical phosphate remover you will need filter socks to catch the precipitate. The chemical Po4 removers remove it fast, but there will be some precipitate that will collect in ur sump and the water will probably go a little cloudy from the precipitate forming. I would get two or three socks to switch change them out every other day, rinse them,hang them to dry and repeat. Good luck with the Po4 battle, stay diligent, u will win in the end!
