I was wondering if anyone has copper water pipes in their home and rearing shrimps at the same time? My home is using copper water pipes. I never really thought about this till my newly added 10 Red Cherry Shrimps died one after another in a matter of 4 weeks. They seem to die right after they molt. They seem to molt fine. Strange thing was that my Amano shrimp has been in my tank for over 1 month before I added my RCS and it is still surving one month after my last RCS died. And to think I was so worried about copper in my ferts since I started to do EI. My fishes are all doing fine. Initially I though it was my low GH/KH and I tried using Sodium Bicarbonate on each WC to increase my KH. Its still at 0 which I believe is due to my ADA Amazonia soil. My tap water has 0KH too. Tap water is 3GH and I add a little equalibrium at WC in a attempt to increase is a little. Its now at 3.5/4 after 2 months of adding equalibrium at each water change. I want to add more shrimps but dun want to end up as last time. Any ideas? Should I just forget about shrimps due to my copper water pipes or it does not matter if the water pipes are copper or steel?
