My shrimps dying too after molting

[murphinvert]

My shrimps are dying after their molting. About my crs that's dying now, I noticed his molt has his red colors on him. My ph is 6.92: TDS: 166, Temp:75f KH:3 GH:4 I use ro water for water changes. 30% a week. What's wrong? Is there lack of calcium? Please help!

IMO that looks like a dead shrimp that was eaten. Meaning, it died and was scavenged by the rest until it appeared in this condition.

i think your GH is low, about 6 might be better

This is the molting of my dead shrimp. I will try to attach more pics later today.
