Marine Depot Staff

How Marine Depot started and how much we have grown.

Marine Depot was started in 1998 by a self-professed reef geek and premed student Ken Wong. Ken envisioned a one-stop shop where customers could find everything they needed, from technical product specifications, reef aquarium information, expert advice on the hobby and friendly one-on-one customer support. Having grown from a one-man crew to being one of the world’s largest suppliers of reef and marine aquarium products, this very core philosophy still lives strong in the Marine Depot culture 17 years later.

Why shop with us?

Tired of waiting days for an email response, calling only to get a voicemail or talking to uninterested order-takers? Here at Marine Depot, we understand how important it is for us to be there for our customers. Knowledgeable and passionate aquarium hobbyists are standing by to answer your questions and to help pick out the right equipment with you by phone, chat or email. We also have over four thousand of your favorite products in stock in our Garden Grove, California warehouse ready to ship out today!

Customer Service Team

Our passion for the hobby.

Every member of our customer service team and many of our support staff are passionate aquarium enthusiasts. This ensures that our merchandise is “hobby-certified” by true fish and reef aficionados. We get as excited as you do in the latest industry trends and innovations. We also enjoy sharing this passion with you.

Customer Support

Being there for you.

Unlike most, we believe that the support we provide to you after the purchase is just as important as the questions we answer for you before the purchase. If you are having trouble setting up your LED lights or are having trouble dialing in your calcium reactor, just give us a call or send us an email and we will be happy to help!

Marine Depot Building

Our future

We strive to continue to be the ‘go-to’ store for all of your aquarium needs. From the support of fellow aquarium hobbyists, we have grown to be the best and one of the biggest in the past 17 years. Being a company created by a passionate hobbyist for fellow hobbyists, we will continue to provide you with the same high level of service and personal care that you deserve for the next 17 years!
