Wondering if any Canadians have experience with these. They got pretty lambasted on reef central because of some truly ridiculous claims by the manufacturer, but as far as I can see they're just a different delivery method for solid carbon.

Things in the tank are bad enough I'm not really worried about testing new things out and I've not been doing anything to intentionally control nitrates since April or May, so I put a bag of them in my sump directly below the outlet of the overflow pipe (I run a durso), so they're getting TONS of oxygen.

In the last week and a half they've turned from snow white to almost red wine colored and the ones getting the most bubbles look like they've dissolved a whole bunch.

So far no negative effects on the inhabitants, and the corals are continuing to tepidly recover from the reno disaster.
