Last year a got a bunch of nice quality cherry shrimp but they all died off over the course of a couple of months.
I initially put this down to the tank not being mature enough but I am about to replace the shrimp and I am wondering if my water is an issue.
My water is reasonably hard (KH5/GH12) and TDS out the tap is ~260 and ~310 in tank (will double check tonight). I do see lots of people saying cherry shrimp are fine in just about anything but also a lot of threads about shrimp mysteriously dying.
I think the main concern is GH and I have read some articles that too high a value means their shell gets to hard and they cannot moult. Is this a valid concern? I don't really want to get into mixing tap water with RO and changing parameters but equally so I don't fancy wiping out another colony....
