I may have missed some of your posts in the past so I'll ask the obvious first: Have you done a planted tank before or is this your first time?
If you've done one before then you should be able to answer these questions:
What are your water parameters, NH4, No3, GH, KH, PH, etc?
How much light are you using?
How long is your photoperiod?
Are you dosing any ferts?
Excel, Co2 or no enrichment?
Filtration of any kind?
Any info would be helpful. Really need some numbers to give you any specific help. If you are worried about the shrimp, NH4 (ammonia) would be the threat you should be concerned about.
