Deb, The author of that review didn't own a marine aquarium at that time. Note his last paragraph
"I would certainly now want to try Marine Environment (which is available locally) if I ever get back into marines."
However, looking at the objectives of the Aquarium Society, they don't exclude marine aquarists from joining do they?

They even have 1 article in the article section on marines.
Well, ok, it looks like the emphasis of the club is freshwater and marine aquarists would not benefit from the club at the moment.
Regarding the salt mixes, let's forget the conclusions made in the RK article about toxins. Do you think the salt composition figures are accurate in both reports? If so, I would like to try the salt mix that is closest to natural sea water.
