The Nautilus DC return pump is an energy efficient and controllable solution for aquarium return pumps. They’re DC- powered and can be adjusted to run as low as 10%. There are 10 different output settings, so you can easily adjust the pump to suit your tanks needs. 3 built in feed timers enable you to choose 10, 30, or 50 minute feed times.

The Nautilus control interface accepts a 0-10v analog DC control input, making it compatible with the Neptune Apex, Coralvue Hydros and other popular aquarium controllers.

Nautilus pumps are available in 7 sizes, ranging from 300 gallons per hour for nano tanks, to 3,200 GPH for large systems. Each pump includes a variety of output nozzle sizes designed to work with vinyl tubing. They can also easily be hard plumbed with PVC. Designed for internal use only. 

The Nautilus DC Pump has a built-in slow start function and runs whisper-silent.

All Nautilus DC Return pumps include a full 24 Month USA warranty.

Aqua-Vault only ships out healthy and pest-free specimens. If something changes with a specimen that is in your order between the time you order and when the coral is shipped out, we will contact you to discuss your options. 

Orders are shipped overnight, Tuesday-Thursday. Orders are packaged and shipped as they are received and you will be contacted regarding your shipment. If you have a special delivery request, it should be noted on the invoice or by sending us an email.  

All corals purchased online are guaranteed alive on arrival. We use specially designed packaging to ensure livestock arrives in optimal condition. If we see there will be extreme weather or other circumstances that will create poor shipping conditions we may request to cancel or delay a shipment.

We recommend having the shipping facility hold your order for pickup. This prevents specimens from exposure to the heat or cold and riding around in a delivery truck. Most packages are available for pick by 10:30 AM. If you select this option, we require pick-up within 2 hrs of arrival. To have your package held at your local shipping facility, please make a note when paying the invoice, or email us immediately after you make your purchase. 

Some species such as Hammers, Torches, Frogspawn, and other similar corals can pull their tissue into their skeleton during shipping. This reverses itself once the coral is placed in an aquarium.

In the rare circumstance you receive a coral that is Dead On Arrival (DOA) you must do the following: 

Send two CLEAR photos of the coral WITHIN 1 hour of arrival time (as noted by the first delivery attempt). All of the following are necessary for the claim to be considered: Photos must be submitted to aquavaultdfw@gmail.com - DOA claims sent via Facebook and Instagram are not valid. Photos must be taken from 2 different angles Item must be SEALED in its original packaging and still be on the original frag plug. Photos MUST be clear.All blue photos are not accepted. Send a CLEAR 20 second video. The video must include: Clear visual of the item in question. The box it was packaged in Shipping label on the box

We may request additional photos, videos, or for the specimen to be sent back to us. DO NOT DISCARD corals or packaging until the DOA claim has been confirmed by us. The customer is responsible for the cost of return shipping. If you have to return your order, we recommend shipping through your local facility.

If your claim is validated, we will issue store credit for the price that was paid for the coral. In the event of a DOA, shipping costs are not refunded. Corals that are part of a giveaway, or are a bonus item that is part of sponsored events are not eligible for DOA claims.

The following are not covered by our DOA Guarantee:

Damage occurring to items during unpacking. Damage occurring to items in unmounting the coral from its base/ frag plug. Damage occurring to items during dipping. Carrier delays due to external circumstances such as mechanical failures, or extreme weather events. 

DOA CREDIT ONLY - NO REFUNDS

Cancellations must be done so within 24 hours of ordering and are subject to a 25% restocking fee. .

I have had nothing but a positive experience with Coral-Vault.com. Kendall and Tyler helped launch me into the hobby, and have been amazing answering questions and providing support. Still have all frags I have purchased, very healthy. Also, very reasonably priced!

I’ve always had an amazing experience with the owner and his store. They have the best selection of high end coral, fish, best prices and excellent customer service! Whenever I have a question, I’m offered a couple different recommendations with pros and cons for each option. The owner, Tyler is fun to chat with and always relates to my woes and successes. The new warehouse looks amazing, I can’t wait for it to open up. I’ve got loads of items to buy!

Some of the best corals out there! Got 5 acanthophyllia, 2 indophyllia, 1 red heart elegance, and a purple cynarina. Can't express how happy I am with the corals and the shipping. Had them in my tank in less than 10 hours from leaving his. Coral health was the best I've seen!!! Some nice freebies too! Can't wait to get my next order from him!

This is the place for high end corals and fish. When i found this place I was surprised that a fish and coral store could be this awesome. They are always playing good music and the vibe is chill. They always have deals going on too. If you live far from this shop you will not regret making the drive. The only sad part is they are moving soon so i cannot wait to visit the new bigger shop.

A coral-buying experience unlike any other! I was recommended by a bunch of my friends to check out this business.

Upon walking in, I was immediately captivated by the amount of tanks, lights, LED screens, and decor, all while being completely surrounded by hundreds of the most beautiful corals I have ever seen!

Tyler and his staff are a team of die-hard hobbyists who understand coral like the back of their hands. I’ll admit that I wasn’t expecting to be as astonished as I was, but one visit to Coral Vault, and you’ll immediately know why they are one of the best saltwater-only businesses in the DFW area.

I’m happy to feel welcome, confident, and certain every time I come in to purchase corals from them.

The store is absolutely awesome and Tyler the owner was extremely helpful. He was honest with me and tried to help me get the right stuff instead of shoving more sales at me.

Will definitely be returning.

Coral Vault is the best shop in the DFW metroplex for high-end corals. Tyler is very knowledgeable about saltwater aquaria and provides great customer service.

I was looking to make my dream tank happen after years of being out of the hobby. I had the display tank built and delivered but after being canceled on by nearly a dozen people I was starting to think my dream tank was going to be a permanent part of my yard.
Tyler and his crew ending up saving the day and moved my 600g beast into her new home. He has gone above and beyond to make my tank reef-scaped and plumbed to perfection.
If you are looking to have a true show-stopping tank you would be a fool not to hire Tyler’s Tanks. His newest storefront is an incredible expansion to his incredible collection of fine corals and ready to introduce fish.
DFW has needed a store of this quality for a long time.
