Hey Jay, any idea why my snails and hermits are very lethargic now. Did another water change today and checked everything but magnesium and everything is within recommended parameters. Have a moderate case of diatoms or possibly dinos on sand and 50% of the rocks. Only thing added to the tank was a cupful of prime 3 days ago when first fish died. Didn't know if I was going to get an ammonia spike. Snails and hermits sitting still for over 24 hours. Other shrimp still moving around somewhat.
