Common Questions

Check here before you email — you might find your answer faster.

1 Can I return a filter I've already used?

To protect the safety of all our customers' livestock, we cannot accept returns on equipment that has been run in water ("wet returns") unless the item is defective. Please read our full Return Policy for details.

2 My filter is making a noise or stopped working.

If you purchased the unit recently, check the impeller for debris (sand, snails, or gravel). If the unit is defective, we can help you start a warranty claim with the manufacturer—just email us with your order number.

3 Do you ship internationally?

Currently, we ship to the United States and Canada. International shipping options may be available for select products—please email us to inquire.
