Bob It is interesting that you made this comment- The problem I have is that calcium carbonate does not dissolve readily and that I would have to age the water and test it to get the right 'hardness'- with CaCl, I can add the correct amount and have the correct doseage without testing or aging my water( Because I worked out the correct dose for our domestic supply)- that way I don't have to have large tubs of water sitting arount my appartment- I would rather tanks with fish taking up space than bins of water taking up space. As far as having NaCl and CaCO3- it doesn't work that way when they are dissolved because each ion is surrrounded by molecules of water. Some might argue that the water may get too salty- but with water changes and the low concentartions I don't see it as a problem. As a side point- if I add the CaCl and the Bicarb at the same time I get CaCarbonate precippitate- which does not dissolve readily- I have to use acid to get it out of my betta jars. I short you are right about the dolomite- but I find my method easier for me. As for the previous post about the snails- I have hundreds of MTS in my 90 plant-dwarf-apitso community tank and had a female borelli that spawned and now has about 20 alevins- I moved her and the babies to another tank b/c I want this first spawn to be successful- - something that would probably not happen in a tank full of hungry fis- the snails didn't seem to bother her. The regani that spawned lost all of her eggs- they were in a clay pot- and seemed to disappear over a couple of nights- even with a light on- I rather suspect that the eggs were not viable- I doubt the snails did it- she is pretty agressive.
