Opinion about Kent Products

[Silverfish]

Don't have any experience with Kent salt, I use IO but I saw an article in a British mag, Practical Fishkeeping I think, and it did a similar salt comparison (or maybe it was the same one) and Kent was given 8/10 and IO was also given 8/10. IO was given the "best buy" or whatever by the testers, but I don't remember anything about phosphates or silicates in the Kent salt. Btw Christy, are there some good aquarium shops in Nanaimo? I was there a week ago on a different mission, but didn't find any. Thanks, Bruce
