DELIVERY INSTRUCTIONS:
Get pond water and have it at room temperature in your house or
basement. Put the snails in the water and let them get adjusted to your
pond water. They are not happy campers when they arrive! They will
appear lifeless from the shock of moving, like a scared turtle in a shell.
As they get active again release them. They have some algae attached to
their shells. This is unavoidable as they get the same growth as rocks and
structures and cannot clean themselves. A few may get cracked shells
during delivery as they get bounced around like little ping pong balls, but
they will mend.

REMEMBER: These are live bearing snails. They only breed a couple of
times a year so don't expect them to multiply fast like regular egg laying
snails. Order according to the size of pond you have. In a normal pond,
Koi and other creatures tend to eat most of the young. If you see new tiny
snails pick them out of the pond and rear them in an aquarium until they
get to at least 1-1½ inches.
In order for your snails to have a positive effect on algae growth you
should have at least 25 for small ponds and 50 or more for larger ponds.
Farm ponds should have at least 200 to have any positive effect. -
