Am I on the right track?

The floc we use is this: http://outdoor-living.hardwarestore....nt-656270.aspx

Being in Canada, I have no idea if you can get it there. But it's most def a liquid treatment. It's worked very well for us when we used it in the past.

Sorry to hear it's such a pain to get stuff delivered to you there! I hope you find the things you are looking for.

edit: I'm sure you know this already, but be sure to vac to waste if you use the floc treatment
