Hi guys, I have had mts for years and love them. For some reason, since moving and using well water, all of them have died. I've check the water and pH was probably 8. It happened in different aquariums, one I even put a piece of coral to help with the calcium. It's been a couple of years since I tried but I wanted to see what could be causing this. BTW if anyone has any that they don't want, I'd love to have them. I just want to find out what the problem was/is.
