So, all things considered, which one do y'all like the best. That is, of course, with respect to the listed data results, price, ease of use (packaging, mixing, etc.), and availability.

I use IO, and I'm not thrilled with the relatively high level of phosphate. Otherwise, it does pretty well comparatively.

I'd go out on a limb and say that Coralife is the best overall, though. I've used it before, and don't remember what it cost. I think I got it on sale, though.

Anyone else have any thoughts?
