ReefDock launched in May 2026 as Reef Trak's built-in shopping layer.

No extra account, no subscription, free for everyone.

Why ReefDock exists

Buying anything for a reef tank used to mean a stack of browser tabs. BRS for additives and dry goods. Amazon for the same dry goods at a different price. Saltwaterfish or LiveAquaria for livestock. Petco for whatever happened to be on sale. Then a Facebook group for hobbyist frag sales. Then a different forum for used equipment. The reef hobby is fragmented across at least a dozen shopping surfaces.

ReefDock collapses that into one search. Type "200 watt return pump" or "Hanna alkalinity reagent" or "ORA Aquacultured Acropora" and you see results from every reef-relevant retailer Reef Trak has integrated, alongside listings from individual reefers selling frags, fish, inverts, and gear they no longer need.

What ReefDock searches

On the retailer side, ReefDock currently pulls from:

Bulk Reef Supply (BRS). Additives, dosing products, dry goods, equipment.
Amazon. General reef-keeping inventory and competing pricing.
Saltwaterfish. Marine fish, corals, inverts.
Petco. Occasional reef inventory at retail pricing.
More retailers landing as ReefDock integrates them.

On the hobbyist side, ReefDock hosts direct-from-reefer listings for corals, fish, invertebrates, and used or new reef equipment. Hobbyist listings can include source-tank parameters, so a buyer knows exactly what conditions a coral grew under. Year-round frag swaps run through the same marketplace alongside the typical "I am upgrading my tank, here is the old return pump" listings.

How checkout works

Hobbyist sales go through Stripe-secured checkout. Buyer pays through ReefDock, ReefDock handles the transfer to the seller. No separate Stripe account on the seller side. No website, no Facebook group post. Just a listing.

Retailer products link out to the retailer (BRS, Amazon, Saltwaterfish, Petco) where you finish the checkout on their site. ReefDock handles the comparison and discovery, the retailer handles the fulfillment.

ReefDock inside Reef Trak

ReefDock lives directly inside Reef Trak on iPhone and Android. The in-app view shipped in Reef Trak 2.2.0 with full navigation, back and forward, dark mode, and smooth page transitions. It is also a standalone site at reefdock.com.

The Reef Trak integration goes past just embedding the site. When you buy something through ReefDock, the purchase auto-imports into Reef Trak's expense tracking. Equipment lands in your equipment records. Livestock lands in your livestock records. Additives and food show up in your dosing or feeding history. The reef-shopping flow and the reef-tracking flow stop being two things you have to reconcile by hand.

Selling on ReefDock

Hobbyists can list corals, fish, inverts, and reef equipment at reefdock.com/sell. Listing is free. Stripe-secured payouts when items sell. Listings can include source-tank parameters like alkalinity, calcium, and temperature, which gives buyers actual provenance on the coral they are getting.

For reef-livestock vendors and shops, ReefDock listings reach the audience actively running Reef Trak as their tracking system, which is a higher-intent crowd than a generic marketplace.

Is ReefDock free to use?

Yes. ReefDock is free whether you have Reef Trak installed or not. Browsing, searching, comparing prices, and posting hobbyist listings cost nothing. Stripe transaction fees apply to completed hobbyist purchases, standard payment-processor fees, not a ReefDock markup.

No Reef Trak premium subscription needed. No subscription at all. The whole site is free.

Frequently asked

What is ReefDock?

It is a reef-supply search engine and marketplace, launched May 2026. Aggregates supplies across BRS, Amazon, Saltwaterfish, and Petco, and hosts a direct-from-hobbyist marketplace for corals, fish, inverts, and used or new reef equipment with Stripe-secured checkout. Lives at reefdock.com and inside the Reef Trak app.

Is ReefDock part of Reef Trak?

ReefDock is built by the same team and lives directly inside Reef Trak on iPhone and Android. Purchases auto-import into Reef Trak's expense and inventory tracking. ReefDock also stands alone at reefdock.com for users who do not have Reef Trak.

Which retailers does ReefDock search?

Bulk Reef Supply, Amazon, Saltwaterfish, Petco, and additional reef-livestock and dry-goods vendors. The list grows as ReefDock integrates more sources.

How does ReefDock compare to ReefBay?

Both have marketplaces, but the value props are different. ReefBay focuses on peer-to-peer trading and a long-established community with strong forums. ReefDock leans on cross-retailer search aggregation across BRS, Amazon, Saltwaterfish, and Petco alongside its hobbyist marketplace. Different tools for different shopping flows.

Does it cost anything to sell on ReefDock?

Listing is free. Hobbyist sales go through Stripe-secured checkout and standard payment-processor fees apply on completed transactions, same as any marketplace. No ReefDock listing fee, no subscription.

Can I include tank parameters with my coral listing?

Yes. Hobbyist listings can include source-tank parameters like alkalinity, calcium, and temperature so buyers see real provenance on the coral they are getting. Especially handy for SPS sellers.

Do I need a Reef Trak account to use ReefDock?

Nope. ReefDock at reefdock.com works without one. If you do use Reef Trak, the integration adds value, purchases auto-import into your expense and inventory records, but it is not required for browsing, searching, or buying.
