Return & Refund Policy
We want you to be confident in your purchase. Please review our policy before ordering.
Last Updated: January 11, 2026The "Wet" Rule — Please Read First
We do not accept returns on any equipment that has been used in water.
Once a filter, pump, or sterilizer has been exposed to aquarium or pond water, it is considered "used" and cannot be resold. This policy prevents the spread of pathogens, parasites, and chemicals between tanks.
1. The "Wet" Rule Explained
- Opened but not used: If you have opened the box but not used the item, you may return it.
- Run in water: If the item has been run in water, it is non-returnable unless defective (see Section 3).
2. Standard Returns (New & Unused)
Changed your mind or purchased the wrong size? We accept returns under the following conditions:
3. Defective or Damaged Items (DOA)
If your item arrives damaged or is "Dead on Arrival" (DOA):
- Contact us at admin@fishtankfilters.com within 48 hours of delivery
- Include photos of the damage and a description of the issue
- We will provide a prepaid shipping label for the return and send a replacement immediately
4. Warranty Claims (After Use)
If your filter fails after it has been installed and running for a period of time, this is considered a Warranty Claim, not a return.
Most of our products carry a manufacturer's warranty (1–3 years depending on the brand). Please contact the manufacturer directly to initiate a warranty claim. If you need help finding their contact information or proof of purchase, email us and we will happily assist you.
5. How to Initiate a Return

- Wait for our Return Authorization (RA) number and shipping instructions
- Ship the item back to the address provided
- Once received and inspected, refunds are processed within 5–7 business days to your original payment method
