Who's using Foz Down & GFO

[annnguyen909]

Has anybody had success using Foz Down to control and eliminate phosphate rather than using GFO and a reactor?

Please comments

Have not read any post here on RS about anyone using it, but did read the below post on a goggle search

That product seems to be a version of lanthanum chloride. There are lots of threads about it in the forum. I think most people use the SeaKlear brand.

Lanthanum chloride works, but it does create a fine precipitate that sometimes seems to kill fish and perhaps irritate corals. Most people handle that by catching the precipitate using a filter sock or some sort of mechanical filter

maybe others can advise...
