@cdaJiv, unfortunately that is a very common problem. The excess food trapped in the substrate also promote planaria and nematodes.
I use a glass feeding dish to minimise the food sinking into the substrate. However, that is not fool proof either, at least not shrimp proof. The shrimp get into the glass feeding dish and kick up a storm, they drag food out of the feeding dish to horde it for themselves. It does help a bit, as the majority of the food is kept in the feeding dish. maybe my feeding dish is too small. A larger dish might work to capture more food, even from hording shrimps. Something like a tea cup saucer sized feeding dish would work, but then it looks huge in a 10gal tank.
Just make sure you place the feeding dish in a calm part of the tank away from the filter outlet.
You can also try feeding them less. Shrimp don't eat much. Daily feeding is unnecessary. Once every other day should be sufficient.
