Dosing Lanthanum Chloride to reduce PO4

[Myka]

There seems to be plenty of "Lanthanum Chloride" products available but from my research, Seaklear was the preferred brand.

Yes, but it's not an aquarium brand. If you're ok with that, give'r.

10 micron filter socks would need to be brought it from the U.S. but they are not hard to find.

Not hard to find - PITA to use. Will clog up very quickly.

I was just hoping others in Canada had some experience with it.

I've used the Brightwell version recently. Years ago I used to use a product that I bought online - can't remember the name, it was "pure" LC. I've never used any LC product in a running system though, only ever in live rock tubs.

Recharging GFO is not something I am interested in doing but I appreciate the suggestion.

Works for me.
