Refund Policy

Returns must be requested within 7 days from the date of delivery (except for non‑returnable items).

All return requests must be submitted via customer service email or our internal contact system within the specified period. Requests received after the deadline will not be accepted.

Products must be unused, unopened, with original packaging and all accessories intact, and in a condition suitable for resale.

For electrical items (e.g., heaters, pumps, lights, filters, etc.), if the product has been powered on or submerged in water, it is considered used and will not be accepted for return without reason (except for manufacturing defects).

Custom‑made or non‑standard size products

Clearance/sale items (clearly marked as "non‑returnable" on the product page)

Opened filter media, sponges, or other consumables (due to hygiene and consumable nature)

Any used, installed, or damaged items (including damage caused by misuse)

If the product has a manufacturing defect or functional failure (not caused by misuse), please contact us within 7 days of delivery and provide clear photos or video evidence.

After verification, we will arrange a free return or exchange and cover the return shipping cost (via our designated carrier).

For electrical items beyond 7 days but still under warranty, we will provide warranty service (repair or replacement of parts). Shipping costs shall be shared as mutually agreed.

Returns due to personal preference, incorrect size estimation, accidental purchase, or similar reasons will be subject to round‑trip shipping fees (including the cost of returning the item to us and the original outbound shipping cost), all to be borne by the buyer.

Returned products must be in perfect condition; otherwise, we reserve the right to refuse the refund or deduct the cost of any damage.

For exchanges, please first return the original item, then place a new order separately. Any price difference will be refunded or charged accordingly.

1. Contact customer service to submit a return request and obtain the return address and an RMA (Return Merchandise Authorization) number.

2. Pack the item securely, ship it back, and keep the tracking number.

3. After we receive and inspect the return, we will process the refund within 3 business days.

4. Refunds will be issued to your original payment account. The actual crediting time depends on your payment provider.

International shipments may incur customs duties, clearance delays, etc. If an order is returned due to rejection by the buyer or an incorrect delivery address provided by the buyer, the return shipping costs and any customs duties incurred will be borne by the buyer.

For non‑quality‑related returns from international orders, all round‑trip international shipping costs shall be borne by the buyer.
