What shrimp are you planning to keep? I wouldn't use Fluval Shrimp stratum, batches are inconsistent in pH buffering. If your keeping neos, I would use Fluval Plant, but shrimp stratum is fine, just buffers to the pH a little low for neos, but then again, that's only for awhile. If your keeping CRS, I would go for UP Shrimp sand (a little expensive) , or Aquasoil.
