Kent Reef Salt Mix
KENT REEF SALT MIX
PHOSPHATE & NITRATE FREE
Kent Reef Salt Mix is a superior blend of all the components necessary to keep marine life healthy in saltwater aquariums .
It is manufactured in one of the finest facilities in the world, ensuring consistent mixes, batch after batch. The facility contains state of the art dehumidifying equipment, hammermills, pharmaceutical blenders and electronic weighing and bagging equipment providing a superb uniform dry mix.
Most other sea salt brands, however fine, only provide seawater levels of trace minerals. In the wild, animals have cubic miles of seawater from which to draw the minerals that they need. In the enclosed environment of a marine aquarium however, animals often suffer because they quickly use up available minerals.
Kent Reef Salt Mix contains enhanced buffer levels ensuring a stable pH and enhanced levels of important minerlas, such as calcium, strontium, iodine, iron, cobalt, rubidium, lithium and many others providing sustained long term results! It includes Coral Vite technology which provides these minerals plus vitamins for the invertebrates.
Some other newer sea salts are deficient in important minerals such as magnesium, many only containing 50% of saewater level!. This saves them money in the production of their salt, but costs the hobbyist! Low magnesium salts cause problems maintaining calcium and buffer levels. Not Kent! Kent Reef Salt Mix has full seawater level of magnesium as well as the proper levels of all other necessary major, minor and trace minerals.
If you want the finest sea salt : buy Kent Reef Salt Mix!

SeaChem Marine Salt
SeaChem Marine Salt's enhanced alkalinity ensures a more stable pH than competing salt blends.
SeaChem Marine Salt possesses excellent solubility characteristics and will provide a clear, ready to use solution in only a few minutes.
SeaChem Marine Salt is a convenient and easy to use one-part formula that is ideal for mixing either small or large batches of saltwater.
Utilizing state of the art production facilities ensures a consistent and uniform particle size that will not separate in packaging or shipping and will provide a consistent saltwater mix every time.
For Reef environments, use Seachem Reef Salt™ instead. It is specifically designed to meet the requirements of a reef system.
SeaChem Reef Salt
It is specifically formulated for the reef environment and will provide ideal seawater concentrations of magnesium, calcium, and strontium with proper alkalinity and pH for closed reef aquarium systems.
It contains all essential major, minor, and trace components found in natural reef waters, but contains no toxic or non-essential components such as nitrate, phosphate, silicate, arsenic, cadmium, or beryllium.
SeaChem Reef Salt dissolves quickly and completely and is ready to use in only a few minutes.
SeaChem Reef Salt will support and promote enhanced calcium and alkalinity stability for those wishing to maintain calcium above Natural Sea Water (NSW) levels (400 mg/L) as well as providing NSW levels of bromide (65 mg/L).
For marine only environments, use SeaChem Marine Salt instead. It is specifically designed to meet the requirements of a marine only (not reef) system.
Additionally, Salinity™ is the most concentrated salt blend on the market. With a hydration level of <0.5% salinity™ will yield a greater volume of prepared saltwater at a salinity of 35‰ per unit of weight than any other salt mix currently on the market.
SeaChem Salinity Salt is identical to the distribution of anions and cations found in Natural Sea Water (NSW). We have compiled data from all the oceans and seas on the Earth, and have targeted the midpoint of the range for each element.
We guarantee to be within ± 5% of the midpoint. For example, at a salinity of 35‰, for calcium, magnesium, and strontium, we have the following targets and ranges.
Calcium: target 422 mg/L, range 400 to 443 mg/L
Magnesium: target 1336 mg/L, range 1269 to 1403 mg/L
Strontium: target 8.4 mg/L, range 8.0 to 8.8 mg/L
Alkalinity and pH values vary widely over the Earth’s oceans. salinity™ will be within the following ranges:
pH: 8.4 to 8.6
Alkalinity: 3.2 to 3.8 meq/L

Tropic Marin
Tropic Marin was first formulated in 1965 and since that time, it has been continuously improved as more precise analytical methods have uncovered the many subtleties of natural sea water. It does not contain any phosphates or nitrates and is manufactured from absolutely pure pharmaceutical grade ingredients, 98% of which are from natural sources.
Using a highly sophisticated process of solid solution mixed crystals, each grain of Tropic Marin contains the exact mix of 70 trace elements found in natural sea water and a unique production process ensures that all these trace elements are maintained in solution, avoiding selective precipitation. Special hydrates are added to ensure super solubility in tap water.
Our packaging is 100% vapour proof which guarantees that no impurities from air or other gases can be absorbed whilst in storage, keeping the salt fresh and lump free.
Tropic Marin Sea Salt is chosen by many of the world's leading public aquariums, professional institutes and hobbyists - it's the natural choice!.
Tropic Marin Pro Reef Marine Salt
The use of kalk reactors and additives strongly affects the water chemistry, which requires an adjustment of the sea salt. Only in considering the combination of all influences, can optimum conditions be created that are both natural and stable.

Reef Crystals
The inclusion of important components at concentrations greater than in natural seawater assures extended availability of substances that are assimilated and depleted especially quickly in thriving reef aquariums. A special additive helps to detoxify excess heavy metals, such as copper, that are often found at elevated levels in domestic water supplies.
Reef Crystals salt provides superior dissolvability and is compatible with all marine aquariums. They use only the most sophisticated biological and chemical test methods to develop and refine their formulas, and Reef Crystals sea salt is no exception.
Every batch is carefully analyzed to guarantee composition, consistency, and uniformity.
