Shipping

Yes, we have CHANGED THE INDUSTRY. We are offering FREE SHIPPING on ALL ORDERS with NO MINIMUMS. Yes that's right. We are not happy with the current status quo. NO MINIMUM ORDER - FREE SHIPPING.

To reduce our shipping costs, all aquarium supplies are shipped UPS, Fedex or USPS. Orders can ship from multiple warehouses throughout the US. We attempt to keep inventory local to you to keep shipping times and expenses low. Our primary warehouses are in PA, TN and AZ. Most orders submitted by 3pm EST (Monday - Friday) are shipped same day. Orders on Friday and over the weekend after 3pm EST will ship Monday unless it's an item that ships out of a 24/7 warehouse. UPS orders will be delivered Monday through Friday. USPS or FedEx will be delivered Monday through Saturday. We deliver pretty much anywhere in the domestic 48 within 3 days FOR FREE!

Returns & Replacements

Personally we strive to never have any. But in the event, we like to make it easy. All returns are accepted within 30 days for any reason. Returns must be requested and pre-approved over e-mail to the sales@saltwateraquarium.com. From there we will email you a prepaid return label. Simply return your item within 30 days for a full refund.
