Shipping & Returns

Return Policy

Return any new, unused product in its original manufacturer's packaging within 30 days of delivery and receive a full money back reimbursement, minus shipping cost and a 20% restocking fee. Product over 30 days old is not returnable for credit.

All returns must have an RA# (Return Authorization Number). This lets us know what is coming back and what to do with it (i.e. credit your account, replace product, etc.). Packages sent to us without an RA# written on them will be refused! All products, including warranty items, must be returned to us shipping prepaid. We will pay the shipping charges on warranty items back to you, but not from you to us. 

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

If you need to return an item, please Contact Us with your order number and details about the product you would like to return. We will respond quickly with instructions for how to return items from your order.

Non-Returnable Items:

  • Special order items
  • Liner
  • Hose
  • Fish Food
  • Liquids 
  • Used items 
  • Open products not in their original box
  • Products being returned after 30 days
