How to care for a pond snail

Updated February 21, 2017

You don't need to spend all your time and money taking care of your pond when you can have pond snails do it for you. Pond snails eat the algae in the water, cleaning your pond and allowing your plants and fish to flourish. These low-maintenance creatures can be your best water-gardening ally. Caring for pond snails is simple, with most of the care going into preparing your pond before introducing the snails to that environment.

Fill a 5-gallon bucket halfway with pond water. Float the bag of pond snails in the bucket for 20 minutes after purchasing them to equalise the water temperatures before releasing the snails into the pond.

Add a chloramines and ammonia remover chemical to your pond 30 minutes before placing the snails into your pond. Follow the dosage instructions on the label -- usually about 59.1ml chemical for every 100 gallons pond water.

Determine how many snails your pond can accommodate. Each adult snail needs about 2.5 to 3 gallons of water. Start with fewer pond snails rather than too many. Add more snails to your pond if the water is still heavy with algae after two or three weeks.

Add calcium to your pond water if the water contains very little calcium. Pond snails need calcium-rich water to build strong shells and to prevent shell damage.


Remove your UV pond filter if you have one installed at least two weeks before releasing snails into the pond. The UV filter kills the algae, which the snails need for food. Monitor your pond and the snails, checking the algae content of your pond and observing your pond snails at least once per month.


Don't trim the leaves on your pond plants too often. Pond snails lay their eggs on the underside of lily leaves, so trimming away these leaves once a month will remove the snail eggs, which look like clear jelly.
