Blue Treasure Marine Salt Brand Overview

Blue Treasure has been producing marine salt and aquarium substrates since 1996, developed in partnership with researchers at the Ocean University of China. The brand holds ISO 9001 quality certification and is used in public aquariums, zoos and reef tanks by hobbyists in over 20 countries. What sets Blue Treasure apart from most marine salt brands is the raw material source. Their sodium chloride base comes from deep underground brine reserves in the Bohai Bay and Huanghai Bay regions of China, deposits that have never been exposed to coastal runoff, agricultural pollution or sewage discharge. This means the salt starts clean before any refining, which is why Blue Treasure consistently achieves zero detectable nitrates and phosphates. At Ocean Paws we stock genuine Blue Treasure products and ship across India.

Blue Treasure Reef Sea Salt

The standard Blue Treasure Reef Sea Salt is formulated for mixed reef tanks keeping soft corals, LPS and marine fish. Calcium and magnesium are elevated above natural seawater levels to account for daily uptake by corals and calcifying invertebrates. The formula includes food grade vitamins and protective colloids that support fish and invertebrate immune health. It mixes clear and reaches stable parameters within 30 to 40 minutes of mixing with RODI water. The correct ratio is 1 kilogram per 28.5 litres of RODI water to reach a specific gravity of 1.024 to 1.026. We stock Blue Treasure Reef Salt with pan India delivery.

Blue Treasure SPS Sea Salt

Blue Treasure also produces a dedicated SPS Sea Salt formulation for tanks dominated by small polyp stony corals. SPS corals consume calcium and alkalinity at significantly higher rates than soft corals and LPS, and the standard reef salt formula cannot keep up in a heavily stocked SPS system. The SPS formula starts with elevated calcium, magnesium and alkalinity levels so newly mixed saltwater already matches the parameters a mature SPS reef requires. This reduces or eliminates the need for additional two-part or calcium reactor dosing in the first weeks after a water change.

Blue Treasure Calcium Sand

The Blue Treasure Calcium Sand is natural aragonite substrate sourced from pollution free zones. Aragonite is calcium carbonate, the same mineral that builds coral skeletons and shells. As it sits in your tank it slowly dissolves and releases calcium and carbonate ions into the water column, naturally buffering pH and alkalinity without dosing. A deep aragonite sandbed also provides a large surface area for beneficial bacteria, adding meaningful biological filtration to your system. It works in marine reef tanks, fish only setups and freshwater cichlid tanks that require elevated pH and hardness.

Blue Treasure Trace Element Supplements

Blue Treasure produces liquid trace element supplements for reef tanks where water changes alone cannot keep up with coral consumption of iodine, strontium, boron and other trace minerals. These supplements are used alongside the reef salt rather than as a replacement, maintaining stable trace element levels between water changes in mature, heavily stocked reef systems.

Frequently Asked Questions about Blue Treasure

Is Blue Treasure Reef Salt safe for SPS corals?

The standard Reef Salt supports mixed reef tanks with soft corals and LPS well. For SPS dominant tanks, the Blue Treasure SPS formula with its higher starting parameters is the better choice. Test your parameters weekly and dose accordingly as coral density increases.

How long does Blue Treasure salt last once opened?

Store in a sealed container in a cool dry place away from moisture and direct sunlight. Moisture is the main enemy. Reseal firmly after every use and the salt remains effective for the duration printed on the packaging.

Can I use Blue Treasure salt for a fish only marine tank?

Yes. The clean formula and balanced trace elements benefit fish only and FOWLR systems just as much as reef tanks. There is no reason to use a different or cheaper salt for a non coral setup.
