Liam check your PH meter.I almost kill all my shrimps because of failure PH meter.
My Akadama is 6-8 months old and it is buffering to 7ph. I’m adding tennis bal size peat moss per tank and it keep PH 5.6-5.8 for 50-60 days.
When I started the tank substrate discharge GH just a little bit. I have 2 tanks with it one CRS and one CBS
There are 20-50 babies in each. Will see how they will do in future.
