Red Sea Coral Pro Salt 7 Kg

Red Sea Coral Pro Salt delivers biologically balanced, elevated foundation elements for accelerated, sustainable coral growth.

Optimal Ratio & Levels Of Elements For Accelerated Coral Growth.

Red Sea Coral Pro Salt contains biologically balanced, elevated levels of the foundation elements necessary for sustainable, accelerated coral growth. Red Sea Coral Pro Salt is ideal for reef aquariums, in particular for LPS and SPS corals, and for growing coral frags. Red Sea Coral Pro Salt is a specialty salt mix formulated for today’s advanced reef aquariums. A scientifically formulated marine salt is based on using pure water. This is a necessary to accurately calculate all the elements required to recreate tropical seawater. It is the best way to create a baseline salt formulation that most precisely mirrors the reef environment. Research laboratories and professional aquaculture facilities often use ultra-pure reverse osmosis and deionized mineral-free water for mixing saltwater. Reef aquarists using RO or RO/DI can have this same level of “saltwater perfection” with Red Sea Coral Pro Salt. Coral Pro Salt is intended to stimulate growth of SPS and LPS corals in aquariums and frag tanks. The coral-building process of calcification demands adequate levels of Foundation Elements: calcium, magnesium and bio-available carbonates. These elements play a key role in coral metabolism and growth, pH stabilization and ionic strength of the saltwater. Coral Pro Salt contains the levels of foundation elements and trace elements necessary for coral growth in your aquarium. You won’t have to use additives to “fix” your freshly made saltwater!

Here’s what we really like about Red Sea Coral Pro Salt:

• Accurately formulated for use with RO/DI water.
• Can also be used with soft water.
• pH stabilizes between 8.2 – 8.5.
• No phosphate or nitrate contamination.
• No need to immediately add extra calcium, magnesium or carbonates.

Red Sea Coral Pro Salt Mix Features:

• Long-term testing proves captive corals demonstrate vigorous growth and vibrant colors.
• Formulated specifically for the advanced reef aquarist using purified water.
• Provides the extra foundation elements needed to promote coral growth.
• Proper pH level quickly stabilizes after mixing.
• Manufactured in small batches to ensure all elements are evenly blended throughout the salt mix.
• Contains all trace elements needed for fish and invertebrates.

The recommended salinity level for reef-building corals is approximately 35 parts per thousand (ppt). At 35 ppt, Red Sea Coral Pro Salt supplies 480 ppm of calcium; the same calcium level required for growing LPS and SPS corals in reef aquariums. The following table shows calcium levels of Coral Pro Salt mixed in RO water for various salinities at 75°F (24°C).

If you have a marine fish and invertebrate, SPS dominant, or ultra-low nutrient system, consider the standard Red Sea Salt Mix formulation. Here is a short video on the product.

See our guide to RODI Water for why pure source water matters for this product's results.

• Pack: 7 kg bucket, makes approximately 210 litres at 33 ppt
• Nitrate and phosphate: none

Setup & Use

Mix with RO or RO/DI water only. Tap water brings in phosphate, silicate and chloramine that the salt cannot correct.

Add the salt to circulating water a little at a time — never pour water onto dry salt. With a powerhead running it dissolves clear in about 20 minutes. Bring the mix up to tank temperature and confirm salinity with a refractometer before it goes anywhere near livestock.

Coral Pro is deliberately supersaturated to carry its higher calcium and alkalinity, so mix it and use it the same day rather than storing mixed water for weeks. For a water change, match the new water's temperature and salinity to the display.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.

Returns & Replacement

Returns are accepted within 7 days of delivery, provided the item is unused and in its original packaging. Manufacturer-sealed items cannot be returned once the seal is broken, and sale-priced items are not refundable.

If your item arrives defective or damaged, message us on WhatsApp with your order number — or email us, if you would rather — and we will replace it.
