  • Formulated from natural seawater chemistry
  • Mixes to 1.025 g/cm3
  • Composed of ACS-and USP-grade ingredients
  • Extensively tested for over three years
  • Manufactured in our own facility
Marine chemists estimate that the chemical composition of seawater has remained relatively constant over the past several hundred-million years (perhaps longer than the last billion years); this stability is largely a result of the immense volume of the ocean and the physical, chemical, geological, and biological processes taking place within it. The so-called “modern day” corals largely responsible for building reefs in tropical marine environments have been in existence for well over 200-million years (soft corals have been around much longer than that!), and more primitive life forms (such as sponges) have been around still longer, collectively evolving and thriving in relatively stable chemical conditions. Recent findings by advanced aquarists and scientists in many countries confirm what has long been suspected: there is no obvious benefit to maintaining the concentrations of calcium and other elements depleted by reef-building organisms at grossly elevated levels; in fact, this practice can be detrimental to their long-term survival. All of these points taken into consideration, it seems elementary to replicate the most important aspects of natural chemical composition of seawater as closely as possible to properly care for delicate marine creatures in captivity. The single most important contributor to success with a marine aquarium is maintaining water parameters within tolerable ranges; no amount of lighting and filtration can compensate for water that is lacking in numerous essential elements and that does not meet the criteria required for survival by marine organisms. A successful marine aquarium therefore begins with quality seawater.

Brightwell Aquatics NeoMarine Salt Mix creates an ideal marine environment for aquarium inhabitants by providing all major elements, all non-conservative (depleted by natural chemical and biological processes) minor and trace elements, and elements known to be utilized in the production of biological pigments (biochromes) in precise natural seawater ratios; all ions are formulated to be present in natural seawater concentrations. Conservative minor and trace elements are not depleted in marine environments, indicating that they are not utilized by marine life or do not take part in chemical reactions in seawater; as such, they are not necessary for the survival of aquarium inhabitants, and are not part of the NeoMarine formulation. NeoMarine is not formulated to have enhanced concentrations of certain elements at the expense of sacrificing others and creating a solution with grossly inaccurate elemental ratios; this formulation is based wholly on current marine science data and extensive testing.

NeoMarine is manufactured in Brightwell Aquatics’ production facility in Pennsylvania, ensuring that we maintain absolute control over quality; NeoMarine is not outsourced as many competing US-manufactured salts are. Additionally, elements are provided by individual salts (no seawater evaporite is used); this enables us to maintain a consistent formulation and appearance to the finished salt mix at all times. Ingredients are measured using an extremely accurate process, and each batch of NeoMarine is blended in a dry, clean environment. Our production process promotes uniformity of particle size and homogeneity throughout each container. Small batches are created and lot numbered to maintain the highest standards of quality control. NeoMarine utilizes ingredients of superior grades, and contains no detectable ammonia, nitrate, phosphate, or organic substances at standard specific gravity. It dissolves completely to create crystal clear water. NeoMarine has been extensively tested over a multi-year period with 100% success on all manner of marine invertebrates, fishes, and desirable algae; numerous species of fishes, corals, and mollusks have reproduced freely when maintained in water prepared with this salt blend. NeoMarine is formulated for all marine organisms, not just fish or reef inhabitants.

Brightwell Aquatics NeoMarine 50 Gallon Salt Mix

Pros: Stable parameters, mixes quickly, and very little sediment, less dosing needing

Cons: Price, but you get what you pay for

Best salt mix I have ever used. Parameters are always stable. Very little sediment and mixes quickly. Although a little bit more money than more money than other salts, you get what you pay for. My corals do so much better with this salt with less dosing.

NeoMarine salt mix

Pros: Consistent

Cons: None

I have been using this product for two years. Consistent high quality. I didn’t know it was available in a box, instead of a bucket until my last order when the buckets were re out of stock, so I got the box. Same price but I have enough buckets now so I will order boxes in the future.

I love this stuff

Pros: I get great results with corals and healthy fish

Cons: None. The price is worth it.

Brightwell is the only salt I use. My LFS sells it mixed and I used that until I got an RO/DI and I continue to use this salt on my own.

Seems to be high quality

Pros: Available, good parameters, lots of users.

Cons: None

Started transitioning to Neo Marine from tropic Marin bioactive. Seems this salt is moderate on price and more readily available than Tropic Marin. Last two times my salt was out of stock, everything seems to be responding good, no crud in the mixing container

Best of the three

Pros: Mixes clear and easy. No residue

Cons: None

Just getting back into reefing. I used two other salts in the past, and was not happy with either. Decided to try something different. I was impressed this time.

The best!

In my nearly 20 years in reefing, I have tried a bunch of different salt types. This one is by far my favorite. Mixes up clear in only a half an hour, and I never have issues with spikes after water changes. I'm sticking with this one from now on!
