CRS dying shrimps
5 months ago I bought 10 crs. Everything was fine. They survived. Two month later bought 20 more and still survived. Then bought 50 more. And since 2 months everything is going bad.
I keep loosing 1-2 shrimps per day. And I do not know what to do. I am starting to lose hope.
My parameters are ph:6.8, amonia: 0, gh: 5, kh: 2. Temperature 23,5
