Anybody...???
You're right, a Ca++ ion is a Ca++ ion, seems that the source shouldn't matter. Perhaps I should look at other possible causes for nerite shell cracks and holes. Any ideas on that one?CaCO3 should dissociate to Ca (2+) and CO3 (-2) ions just like any other calcium salt so I don't see why there would be a difference in absorption - it should be the same ion.
Thanks for the offer Edward, but I have plenty of Ca in my waters, too much actually. I assume Randy-post got you the petites ok.Hej Bert, I have a bag of pelletized dolomitic lime. If you would like some, I will send it to you by Randy-post Just say it...
Regards
Edward
