marine salts

[BCOrchidGuy]

Steve s, that chart you linked to is the republished S-15 report, strangely enough with out the Aquacraft stuff on there. I got an email back from Kent today and the scientist assures me that the concentration of copper in Kent salts is very very close to that of NSW, a slight variation between batches will be obvious but NEVER 50 times that of NSW. The scientist at Kent feels that at a concentration that hi, inverts would suffer and most likey die over a short period of time.
