5. Red Sea Fish Pharm ARE22033 Reef Foundation Magnesium Supplement-C for Aquarium, 500ml

Feature

Reef Foundation C Contains Blended Salts Of Magnesium And Is Part Of Complete Reef Care System
Calcium, Magnesium, Strontium And Carbonate Are The Basic Foundation Elements Of Coral Skeletons

Description

Red Sea calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for coral health and growth. Reef foundation C contains blended salts of magnesium and is part of complete reef care system. 1-mL of reef foundation C will raise the magnesium level of 25-gallon of water by 1 ppm.

6. Reef Advantage Magnesium, 4 kg / 8.8 lbs

Feature

Raises Magnesium And Contains No Ammonia
A Concentrated Optimized Blend Of Magnesium, Chloride, And Sulfate Salts Designed To Restore Depleted Levels Of Magnesium
Minimal impact to the ionic ratios found in natural sea water
Contains No Ammonia, A Common Contaminant In Every Liquid Magnesium Supplement On The Market
300 Grams Treats 1200 Us Gallons

Description

Reef Advantage Magnesium is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Reef Advantage Magnesium contains no ammonia! This is a common contaminant in every liquid magnesium supplement on the market. Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser. DO NOT OVERDOSE: Excess magnesium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if magnesium & carbonate additives are added on alternate days or at least 30 minutes apart. Slight clumping of this product may be encountered but does not impact its use; any clumps will break up very easily. Guaranteed Analysis: Magnesium (Mg) 8.00%

7. Kent Marine 00412 Tech M Magnesium, 16-Ounce Bottle

Feature

Ionically balanced
Raises the magnesium level in any marine system
Nitrate, phosphate and gluconate free
Not for human consumption

Description

Tech M Magnesium supplement is a ionically balanced product which will safely raise the magnesium level in any marine system without upsetting the ionic balance of the system. Tech M is very concentrated, containing over 70,000 ppm of cationic magnesium, and is nitrate, phosphate and gluconate free. If you have trouble maintaining calcium or buffer level, check to see that the salt mix you are using has seawater level of magnesium. To save money and increase dissolvability, some manufacturers of popular newer salts have included only half the level of magnesium necessary in their sea salt mixes, resulting in low calcium solubility and poor buffering. Tech M Magnesium supplement will provide the magnesium left out by salt manufacturers or increase the magnesium level in any system. This will provide for easier maintenance of alkalinity (buffering capacity) and calcium level.

Description

Overview Highly-concentrated ionic magnesium solution. Provides magnesium, which helps regulate the balance between calcium and carbonates in aquarium water, and is a component of aragonite, the mineral secreted by reef-building organisms such as corals, clams, and their allies to form skeletal material. Stronger than most competing products. Contains no unwanted organic material such as EDTA, gluconate, or polygluconate. Formulated by a marine scientist.Technical BackgroundMagnesium plays a vital role in reef aquaria: it helps maintain calcium and carbonate (composing the majority of measurable alkalinity) concentrations by limiting unwanted inorganic precipitation with each other. In the absence of adequate magnesium ions, calcium and carbonate ions bond rapidly, depleting their concentrations in the system and creating the false impression that heavier supplementation is required to re-establish the desired concentrations. No matter how much calcium is added, its natural seawater concentration of 412 ppm will never be sustained until the magnesium concentration begins to approach 1,290 ppm. Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results. Keeping magnesium within a range of 1,290-1,320 ppm will maintain the desired balance, and provides enough of the element to reef-building organisms for the formation of aragonite (~0.10% Mg by weight).The rate at which magnesium is 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 magnesium supplementation. Once the rate of magnesium uptake in the aquarium has been determined, the proper dosing rate of this product can be easily calculated. It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements
