Reef Salt 25kg BOX

This 25 kg box of synthetic marine salt is intended for reef aquariums, where the aquarist needs a salt mix that delivers a defined ion profile for coral growth and colouration. Its composition was selected by the manufacturer to support marine invertebrates and corals, and it is suited to keepers who want to match a set of published water parameters.

Why it matters

• The mix contains micro and macro elements that the manufacturer states cover the requirements of corals for growth and colouration.
• The manufacturer states the formulation is free of bromides, and the water is compatible with ozone-assisted filtration.
• A ready reference of target values is provided for chloride, sodium, magnesium, sulphur, calcium, potassium, strontium, iron, fluoride, bromide, dKH and pH, allowing the result to be checked against those ranges.
• Instructions specify a mixing temperature of about 24°C, around 15 minutes of vigorous stirring, and a wait for full clarity before use. A new tank should not receive its first animals earlier than 10 to 14 days after filling.

What it works with

The salt is intended for marine reef setups in which corals and other marine invertebrates are kept, and it is prepared with demineralised water as the base. Volume is set by the dose rate, so the 25 kg box corresponds to roughly 630 litres of 34 PSU water at the stated ratio. The manufacturer's ozone compatibility note applies to the filtration side of the system.
