Standard snail water solution

Don't keep snails in tap water - snails don't like tap water in York as it kills them. I keep snails in standard conditions, for scientific experiments, and this means keeping them in a standard snail water. This contains calcium to help them with their shells, and some other salts. It is easiest to make up concentrated solutions which will keep for several months and dilute these as needed.

All the chemicals for standard snail water can be safely used with good laboratory practice and fall in the Biology Safety category A. Click here for details

Diluting the concentrated solutions for use
-This makes 30 liters
  • Put about 15 liters of distilled water in the tank. 
  • Add 60 ml of A using a plastic measuring cylinder
  • Rinse the measuring cylinder into the tank 3 times with distilled water
  • Add 60 ml of B
  • Make up to the 30 liter mark.

To make Solution A Weigh 11g NaHCO3 and 6.6g K2SO4 and use a magnetic stirrer to dissolve together in 400ml distilled water.
To make Solution B Weigh 59g CaCl2.2H2O and 10g Mg(NO3)2.6H2O and stir to dissolve in 400ml distilled water.

This Standard Snail water for Lymnaea is based on that described by Thomas et al (1986) Comp. Biochem. Physiol. 83A:457-460 for Biomphalaria.
