I have a heavily planted tank, which i dose with PPS-Pro. one for macro, one for trace, but the trace i use have Cu inside it. so i was worried at first, but the shrimps looks ok.

However, last week i got some high grade CRS, the first week they seems fine, but then some died. My low grade CRS and cherry all seems fine, many heavily pregrant. so do u think i should stop dosing, esp the trace?

Many thanks

For what I know Cu is very harmful for all kind of invertebrates. Probably the fisrt that will notice it will be high grade CRS, as they are more fragile.

I would stop dosing that product. You can find many products without Cu.
