Maybe this is an open letter to the masses. I'll bite
I have two pails, one if free only catch it's a solid block, came like that and was replaced for free with the second pail I have. The second is 90 percent full and fine. Only reason I don't use is I believe it adds too much "bio" for my skimmer to deal with. Second pail is 50$.. I might be in Saskatoon on Friday if Colby posts corals on facebook. Hint hint Colby.
