Liquid carbon supplements are not safe, in my view. I don't know if they can affect shrimp, but it wouldn't surprise me. They certainly affect fish and plants.
API CO2 Booster and Seachem's Excel are the two most common types of liquid carbon supplement. Both are nearly identical, containing glutaraldehyde and water; Seachem says their product is polycycloglutaracetal, but this seems to be their version of the same thing, since the Material Safety Data Sheet for Excel lists glutaraldehyde as the ingredient. This substance is a powerful toxin used in hospitals to sterilize, in embalming fluid, in antifreeze, and to disinfect ship ballasts when they move from one ocean to another to avoid carrying pathogens and bacteria. In the aquarium, some plants are killed at the normal dose. No wonder it can kill brush algae on contact. It is also a health risk for humans in several ways. I won't use it.
The bubble wand may be driving out needed CO2. There is no evidence from scientific tests to prove the contrary, so I still hold that it probably does. During night, CO2 builds in a natural planted tank, and then when the light is on during the day, plants use this as their much-needed carbon source. In a balanced planted tank, there is no way the fish will have any oxygen depletion, so I would not use any such device.
