that is very similar to my water, moderately hard to hard. It should be great for neocaridina species as well as snails.
well hopefully soon I will know if it is the food or not. since I have no more shrimp to test it on a kind soul has traded with me and decided to try the "death sticks" lol... so will know in a week or so! I shall have a new batch of wild neo's and hopefully all will be well after a few water changes!
oh... will try not to forget the new GH kit
It's quite possible your tap water had a dose of chloramine (or something else) added for some reason known only to the water treatment folks. They never publicize the fact that they're dosing chemicals for whatever reason, but they do it occaisonally whether intentionally or by accident.
Any fertilizers in the tank?
I agree there had to be some contaminent..
