  • Shipping Lower 48 States

  • Complete source of the elements and molecules that are directly used by corals, clams, and other reef-building invertebrates and organisms to create skeletal material and grow.

  • Provides calcium (140,000 ppm), strontium, magnesium, and potassium in approximately the same ratios* in which they occur in aragonite.

  • Very strong source of carbonates (derived from aragonite).

  • Increases alkalinity to help stabilize pH.

  • Stronger than competing products.

  • May be used as an inexpensive alternative to automated calcium reactor systems

  • Free of phosphate, silicate, and organic material.

Technical Background

Brightwell Aquatics Liquid Reef has twice the calcium relative to carbonates as compared to natural aragonite, making it a very powerful calcium source. The active components of Liquid Reef are provided by a combination of sources and include natural aragonite, increasing the solubility of the solution and the effectiveness of the method. Silicate- and phosphate-free. Examples of reef-building organisms familiar to hobbyists are: stony corals and their allies; molluscs including clams (bivalves) and snails (gastropods); tube worms that secrete calcareous burrows; and calcareous algae such as coralline, Halimeda, and Penicilus. These organisms require that the components of aragonite be in adequate concentrations if they are to thrive, regardless of how perfect the remainder of their environment is.


The advantage to this method of supplementation is that one product may be used to establish and maintain water parameters conducive to reef formation. Note that target ion-specific supplementation may be called for in some aquaria, depending upon stocking density of reef-building organisms and environmental conditions within the system. Additionally, hobbyists may choose to use Liquid Reef in conjunction with other methods of calcium, strontium, magnesium, and carbonate supplementation as a means of diversifying their dosing routine. The rate at which calcium and carbonates are extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other conditions; therefore, each aquarium will have different requirements for the rate of supplementation.

*Aragonite composition is seen to vary slightly between regions; the specific ratios of target ions in Liquid Reef are based upon data available for aragonite originating in the Tropical Atlantic.

Instructions and Guidelines

Basic: Shake product well before using. Add 5 ml (1 capful) of product per 50 US-gallons of aquarium water every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 250 ml treats up to 2,500 US-gallons (9,464 L). Liquid Reef may temporarily cloud aquarium water after addition, therefore it is recommended that the product be dosed at night.

Advanced: Determine the calcium concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before each use. Liquid Reef may temporarily cloud aquarium water after addition, therefore it is recommended that the product be dosed at night. Each ml of Liquid Reef will increase the concentration of calcium (“[Ca2+]”) in 1 US-gallon (3.785 L) of water by approximately 37 ppm. If the initial [Ca2+] in the aquarium is below 412 ppm, add this product at the maximum rate of 10 ml per 30 US-gallons daily until the desired calcium concentration is attained, then dose daily or weekly as needed (see below). Always try to maintain the [Ca2+] within a range of +/-10 ppm. To determine the dosing rate of this product once the desired [Ca2+] has been acquired, measure the daily rate of calcium uptake (i.e. the decrease in calcium) in your aquarium by measuring the [Ca2+] at the same time each day over a one- to two-week period. To determine the daily dosing rate (preferable to weekly dosing) for calcium maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in [Ca2+] by 37; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [Ca2+]. Daily dosing maintains a more stable [Ca2+] (and more natural environment) than dosing weekly, in which the [Ca2+] spikes just after dosing and then gradually decreases throughout the course of the week.


Caution: May cause eye or skin irritation. Flush with water for 15 minutes if in eyes, seek medical attention if irritation persists. Keep out of reach of children. Not for human consumption.

Coral 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, Monday-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 . 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 questionThe box it was packaged inShipping 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. 

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 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!

Bert Blank

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!

Sunday was my first time to visit Tyler & Josh and let me say I have never seen such a bright and beautiful collection of corals. I absolutely love the ambiance at Coral-Vault!!! Thank you again for helping my husband and I find some amazing additions for our tank. I can not wait to come back!!!

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.
