Hiker Ocean SPS Reef Salt 20kg

Description

Hiker Ocean SPS Reef Salt 20kg — Bulk synthetic sea salt mix for SPS-dominated reef aquariums

A reef full of small-polyp stony corals draws on calcium, alkalinity and magnesium every day, and each water change is a chance to put some of that back. Hiker Ocean SPS Reef Salt 20kg (SKU: HK201103) is a synthetic sea salt mix sold under the Hiker Ocean name and labelled for SPS reef aquariums, supplied in a 20 kg pack for mixing saltwater at home. A salt mix like this is dissolved in purified fresh water to make new seawater, both for filling a new system and for the routine water changes that keep an established reef stable. The maker’s mixing rate and target parameters are printed on the pack and should be followed in preference to any general guide.

Reef salts are mixed in RO/DI water rather than tap water, because tap water can carry phosphate, nitrate, silicate and metals into the tank. Most reef salts need roughly 33 to 38 g per litre to reach natural seawater salinity, so a 20 kg pack typically makes somewhere in the region of 520 to 600 litres, depending on the mix and the salinity chosen; a refractometer, not the scoop, decides the final amount. Mix in a clean, food-grade container with a circulation pump and a heater, add salt to the water rather than water to the salt, and allow several hours or overnight for the batch to clear before checking salinity and temperature. Testing alkalinity, calcium and magnesium on a fresh batch shows exactly what each water change adds to the reef.

Usage & Application

When to Use

• SPS reef aquariums: New water for systems dominated by small-polyp stony corals.
• Routine water changes: Weekly or fortnightly changes on established reefs.
• New system fills: Mixing the first batches for a new marine tank.
• Larger systems: A 20 kg pack for big displays or frequent changes.

Mixing & Application Guide

• Start with RO/DI water: Purified water brought to about tank temperature.
• Add salt gradually: Pour it into moving water to stop clumping.
• Let it mix: Circulate for several hours, or overnight, before use.
• Match the tank: Bring salinity and temperature to the display’s values before the change.
