Hi Nick,
I don't think you have isolated the cause for the deaths. Good to hear maybe they have slowed down.
There is something seriously amiss though because I have kept cherries in 0-30 degrees, 0 to very hard water, low to very high CO2, 60% water changes with temp fluctuations of 5 degrees. Once I left some in a bucket in my shed which goes down to -2 during winter with no filter etc and they still survived and even bred a little. The very same shrimp dropped like flies when I put them in a Fluval edge I bought second hand. I could never keep ANY fish or shrimp in that tank no matter how hard I tried for 3 years. I have never been happier to find a tank leaking one day! I never reused that filter.
I am confident that the shrimp are now doing well, berried females are a good sign. Hopefully, I can now start enjoying the tank more 🙂
With the help of the forum, I have ruled out anything catastrophic such as copper or other water parameters. I think a big issue was trying to do everything as others were, or I had seen on the web, I have not settled into a routine that seems to be working for me.
No bother at all 🙂Curious to know if you ever got to the bottom of the Fluval Edge issue? (apologies to Nick for the tangent)
