Quick Overview

NeoMarine Salt Features:

  • Extensively-researched and tested over a multi-year period, with a formulation based on current understanding of Marine Chemistry and Marine Biology as they pertain to the husbandry of all marine aquaria (e.g. reef, mixed reef, FOWLR, fish-only, mangrove, sea grass, lagoonal, brackish, etc.).

  • Precision-formulated to replicate the natural seawater ratios of every major element, as well as all non-conservative minor and trace elements.

  • Creates a marine environment so chemically-similar to natural seawater in all important respects that aquarium inhabitants are not likely to discern any difference between water prepared with NēoMarine and filtered natural seawater from tropical reef waters.

  • Contains USP- and ACS Reagent-grade ingredients.

  • 134 g per 1 US-gallon (3.785 L) of purified water yields a specific gravity of ~1.025 g/cm3, with a pH of ~8.30 and alkalinity of ~7.5 dKH.

  • Manufactured by Brightwell Aquatics in their own production facility (not outsourced) under the strictest standards of quality. Every batch is lot numbered and sampled for quality control.

  • Utilizes a production process that promotes particle size uniformity and a dry, homogenous salt blend.

  • Formulated by a marine scientist; not composed of seawater evaporite.

What’s in NēoMarine:

  • Anhydrous-only forms of major elements

  • Average Mg, Ca, K, and Sr concentrations of 1,290-, 413-, 399-, and 8 ppm, respectively

  • All non-conservative minor and trace elements found in seawater

  • Sufficient salt to reconstitute purified water of the stated package volume to 1.025 g/cm3

  • Our commitment that this salt blend is the best you have ever used

 What’s not in NēoMarine:

  • Anti-caking agents

  • Vitamins, amino acids, and other unnecessary organic substances

  • Hydrated forms of major elements such as magnesium and calcium

  • Saltwater evaporite (e.g. dehydrated saltwater)

  • Ammonia*

  • Phosphate*

 *Ammonia and phosphate are undetectable in water prepared to 1.025 g/cm3 using Hach standard test kits with reagents within the usable dates.  Every batch is tested and results are logged.

Mixing Instructions

Do not mix in an aquarium containing live organisms. NēoMarine creates slight heat when mixed into water; therefore, do not handle dry NēoMarine with wet hands. NēoMarine may have a slight sulfurous odor when the container is first opened; this is a result of the use of anhydrous magnesium chloride and will dissipate.

It is strongly recommended to use Reverse Osmosis Deionized water when mixing NeoMarine Salt.  To mix saltwater with a specific gravity of 1.025 g/cm3 add approximately 1/2 cup (134.5g or 4oz) of NeoMarine Salt per gallon of RODI water and adjust as necessary by adding more salt or water to reach desired specific gravity.
Allow the freshly made seawater to mix for 24 hours with a submersible powerhead or pump.  Ensure that the water temperature matches that of the established aquarium (use a submersible heater if necessary). Allow water to mix, preferably while being aerated, until pH becomes completely stable, indicating that gas equilibrium has been achieved. It is strongly recommended that at least 24-hours of mixing be allowed to pass before adding the water to an established aquarium; this extra time enables gas formed during the salt dissolution to escape, further stabilizing alkalinity and pH. Note that water temperature and mixing rate will influence the speed with which the salt goes into solution. It is recommended that 10 - 20% of the total water volume in an aquarium system be replaced every 7 - 10 days; this helps maintain proper water chemistry and consequently benefits aquarium inhabitants.

How was NeoMarine formulated?

Basically, we reverse-engineered saltwater by creating an extremely-precise calculation method that takes into account all necessary chemical characteristics of the salts that provide desirable elements.  Natural seawater concentrations of all major elements, as well as the minor and trace elements that are considered to be non-conservative (e.g. they are utilized in biological and chemical processes that occur in marine environments), were used as the design template. We then tested several combinations of ingredients that ultimately provided identical concentrations of each important element (except chloride, which was the only ion that varied in concentration); we were specifically interested in assessing the dryness and homogeneity of the blend, as well as the solubility and speed with which the blend completely dissolved into solution.  For what it’s worth, the final formulation provides all major, minor, and trace elements at concentrations within 0.000001% (with the exception of chloride) of their respective average natural seawater concentrations.  We strive to reproduce this formulation with our production process.


How was NeoMarine tested?

Once we had arrived at a final formulation, we tested it in multiple research systems for a period of three years.  Our research systems house all conceivable types of marine fishes, cnidarians, bivalves, gastropods, echinoderms, crustaceans, coelenterates, and poriferans, as well as ancillary organisms such as suspension-feeding worms, macroalgae, sea grasses, and mangroves.  We have exclusively been using our salt formulation on every system during the three-year testing process, with remarkable success: several coral spawning events have taken place, fishes have reproduced, and the coloration and apparent health of all residents in the systems is very good.  Additionally, NeoMarine has been successfully used in a large reef aquarium on display at a prominent national museum in the Nation’s Capitol.


How is NeoMarine manufactured?

We’ll give you a hint: no cement mixers are used!  The exact process is deemed proprietary, but what we can divulge is that the process is such that a homogenous particle size and blend are created in a clean, climate-controlled atmosphere within our own production facility.  Rather than producing several tons of NēoMarine in each batch, we create batches of modest-size that enable us to maintain maximum quality control and ensure the most homogenous blend; the more ingredients that are used, the more difficult it is to create homogeneity throughout the finished product (our formulation makes use of nearly 40 ingredients, for reference), so producing gigantic batches of salt is not an option for us.  If we were just blending table salt with “ice-melt” and Dow flake and calling that a finished product, we could make multi-ton batches and not lose any sleep doing so.


How long does it take for NeoMarine to dissolve?

On average, 75°F water that has the proper amount of NēoMarine added to increase the specific gravity to 1.025 g/cm3 will clear in less than 15-minutes with vigorous mixing, however when mixing a large batch (e.g. ≥50-gallons) all at once it may take longer for the mix to completely clear.  Two things factor into the speed that a salt mix will clear in water of a standardized temperature: the degree of mixing taking place within the mixing vessel, and the solubility of the various salts that are present in a mix.  Regarding the former, it can be said that the speed of dissolution is directly related to the amount of water movement in the vessel; that is, faster water movement decreases the time required for the mix to completely dissolve and clarify, assuming that samples are prepared using the same salt blend.  Companies selling sea salt blends have been hyping the speed with which their salt dissolves completely for so long that aquarists now use this as a bench-mark to judge the quality of a salt mix; ironically, salts that mix immediately into water are typified by low concentrations of magnesium, calcium, and/or the use of a large percentage of highly-soluble hydrated ingredients that drag unwanted substances into their final product (see the following section).  Honestly, salt water should mix overnight in order to allow all intermediate gasses formed during the dissolution process to escape and pH and alkalinity to become stable.  If the newly-mixed saltwater doesn’t become crystal-clear within 30-seconds, who cares?

  • Superb Reef Salt By FLSharkvoctim on 10/29/2017

    I have used many different brands on the market, Instant Ocean, Fritz Reef Pro, RedSea Reef Pro etc, etc Started using this salt and all of my SP's corals and my LPs corals are doi g great with this salt! PH, salinity is always spot on! U own a mixed reef tank I would highly recommended reef salt
  • Mixes well , Close to crystal clear By Charles on 6/26/2017

    I bought my first bucket of this a couple weeks ago and I can assure you it will not be my last. The mix dissolves completely and dissolves quickly. I have used a couple other brands that took what seemed like forever to dissolve. After doing my water change the cloudiness was not their as it is when I used my old brand.I have crystal clear water in a matter of minutes , which is something I really like about the Brightwell salt. Shortly after the water change I checked the ph and it was right back to my normal 8.1 . All in all I can confidently recommend this salt to everyone I know.anyone
  • best store best product By h on 3/29/2017

    Been in the reef hobby since 1990. I've used most all mixes. Neo marine has Beebe the best at keeping parameters. Very consistent between each bucket. Would highly recommend for all mixes to stir/mix as content settle due to different molecular weights. *** bulk reef is the best! Customer service and prices are the best!
  • Thumbs Up By Nick on 3/21/2017

    Mixed reef responding well to the new salt. Smells funky and takes a few minutes longer than others to dissolve. Nice and clear in less than an hour, with no undissolved solids in the bottom. I mix 50 gallons at a time and wait a day or so before I use any prepared water. Alk measured at 7.8. Everything responded well to 40% change -I consider a good water change when nothing in the tank notices... All the corals stayed open and a week later nothing to report but a happy reef. For reference... I got my first acropora in 1993, and have had pretty much acro dominated tanks since then.
  • The Only Salt I'll Use By Jeffrey on 1/16/2017

    I was using HW-Marinemix Reefer salt for a little over a year. Two issues I was having was the slimy brown film left behind after mixing. All salts leave some kind of residue but I never had a slimy residue. It's fair to assume this slimy stuff was going into my tank. The second issue that I noticed was my ORP would immediately drop on my Apex controller on average by 70 and would gradually climb back up to the low 320's by the next weekly water change. The last time I used it, the newly mixed water had a slight brown color. (mix in white bucket) and 1/3 of my corals started to have STN. within days. They are now dead. Sense switching my corals seem to be much happier. Corals love stability. My ORP now drops by 23 to 30 and rebounds within 2 hours max. After the first few water changes my ORP now stays around 425 on average with the highest reading of 455. By the way I do not use ozone. Everything is happy in the tank and I can't say enough about this salt.
  • Not the best By Me on 12/10/2016

    I've been using this bucket for a few months now for water changes. Every time I've performed a water change shortly after I've lost some coral. Looked further into it, and Alkalinity isn't mixing at 7.5 dKH as advertised, it's mixing anywhere from 6-6.9 (according to Hannah Checker). I've also had algae problems since using this salt, while changing no other variable. Wouldn't recommend this salt to a friend.
  • Pretty much killed my whole tank By Bucky on 11/9/2016

    I went through one bucket and saw a massive algae bloom. I thought I had caused it somehow by over feeding. I slowly removed all of the variables. All but one piece of coral died. More than half of my fish died. By the time I figured out that it was this stinky salt causing all of the problems, I was into my second bucket of it. (bought on a "special"). I just did a partial change using red sea and the fish and remaining piece of coral are reacting well. It is going to take several more and a lot of cleaners and a lot of work to get to where I was before I bought this. Do not buy it if you like your tank.
  • good salt By Chaz on 9/15/2016

    Corals are looking great. Started using Neomarine about six months ago. I am having a lot less problems with algae.
  • Good consistency By Bob E on 7/16/2016

    Salt clears in mixing tank quickly. Leaves very little sediment over time. Company stands behind product. The smell has nothing to do with the quality of salt. I have always mixed my salt with air for at least 24 hrs. The smell is gone in 2 hrs. The smell has to do with the way they pkg the magnesium. All said, I've used several salts over the past 15 yrs., they all seem to support marine life. The more expensive salts don't seem to out perform the mid priced salts, but the cheaper salts do seem to leave more sediment in the mix tank. This is a good quality, medium priced salt that works for me.
  • great! By jolson on 4/8/2016

    Ive used this salt in the past but when i got back in the hobby i used reefcrystals to fill my tank and get it going. ive had nothing but problems with low PH (7.8-8.0 max) and calcium and alk. i had to dose kalk+2 in my top off to make up for the lack. Since i switched to neomarine my PH is now at a steady 8.1-8.2 and my coraline algae growth has exploded and my sps has never looked better. i dont know why i even tried using reef crystals knowing that this is the stuff that used to do me good back in the day before i left the hobby. If you are having problems with low ph calc and alk i suggest switching to neomarine. everything in my tank looks so much better now and growth is almost double what it was while using reef crystals.
  • Smells Awful, and corals didn't like it. By Keo05 on 3/31/2016

    I got some Neo Marine salt when BRS was having a sale. The first big difference I noticed was the smell. It reminds of Prime water conditioner. Then, after a couple water changes, my tank looked worse with the new salt.
    So, I switched back to reef crystals. Recently I started doing half and half to see what my results would be. The tank didn't have a big set back like before. However, as the amount of water turned over, I noticed that the water began to smell like the bucket.
    I'm done with the bucket of salt (as much as I hate to throw away expensive salt). I'm not sure if I got a bad bucket, but I wouldn't recommend it.
  • Best salt on the market By ScarmO on 3/25/2016

    This is hands down the best salt available on the market. My corals absolutely love it and I would never use any other salt after using brightwell.
