Shell attrition

Hi all,
they “dug wells” for the source and that they “soften” it. It feels slimy to the touch and tastes like baking soda has been added to it. Needless to say, we don’t drink it.
OK, that helps, they use <"sodium carbonate softening">.
Much better. But better still, powdered calcium carbonate. It's "insoluble" and will make the water cloudy, for some hours. But fear not, it's harmless and it will dissolve.
Personally I'd go down that route. Can you get <"Oyster (or Cockle) shell Chick grit">?

If you can't? the potassium carbonate (K2CO3) is fine.
...... 1.2g K2CO3 in 25 litres of water = 2 dKH

Ahhhh, the Louisiana drinking water article … I don’t live on the coast but is it possible that my water source is from a well that has saline in it? Where I live, there used to be a “saltwater natatorium” that was fed by a saltwater well. Interesting stuff here.

Ok. I’m tossing the baking soda. I only have potassium carbonate on hand now but will order the calcium carbonate. And, yes I measure it when mixing. I go by TDS to get me close then double check with liquid test kits.
I think I found the chicken grit. It’s called Dumor Oyster Shell chicken calcium supplement. Ingredients are oyster shell and coral calcium. Pellet sized crushed oyster shell. Heat treated for purity. Active ingredient is oyster shell. Is this the right stuff?
Hi all,
Dumor Oyster Shell chicken calcium supplement
That sounds right and hopefully pretty cheap? (a couple of $ a pound?) you should be able to find some that costs "chicken feed".

You just need to add a little and see how long it takes to dissolve (you can put it in a net bag in the filter, or the tank, etc). If it doesn't dissolve? your Ramshorn snails won't either. If it dissolves rapidly, just add some more.

Wow, that sounds easy! So I will leave my RO at 0 Kh? And just add the Ca/Mg to get the Gh to 8 and call it done?

And, yes, cheap. 5 pounds for $8.

Yes. Just add a couple of pellets of the Oyster shell chicken feed to the tank and see how the snails get along.

They won't be able to repair the damaged shell, but hopefully they should be all right. I use rain-water and the Ramshorn snails <"never get very big, or very old">, but they maintain themselves as a population.

Ok, got the crushed oyster shell pellets. When you say to add a couple of pellets … how many per tank size? I have 20, 40, and 100 gallon tanks. Thanks.
