Add Sea-90 Complete Sea Salt to dechlorinated tap water or purified water.
Mix vigorously, aerating mixture until pH and oxygen are stable.
We recommend mixing a few hours prior to use to allow marine snow (sandy silt) to naturally settle to the bottom.
Before adding to your tank, check specific gravity, pH, and temperature levels.

Sea-90 can be used to recreate seawater or brine water in aquarium tanks or aquaculture ponds. Sea-90 supports all forms of marine life.

Dissolving 1/2 cup (approximately 130 grams) of Sea-90 Complete Sea Salt in 1 gallon (3.8L) of purified water at 78* F will result in a seawater mix of:
Specific Gravity: 1.021 - 1.024 / approx. 28 ppt - 32 ppt salinity
pH: 8.0 - 8.2

Approximate Per Gallon Use:

10 Gallons: 3 Lbs.
25 Gallons: 7.5 Lbs.
50 Gallons: 15 Lbs.
100 Gallons: 30 Lbs.
150 Gallons: 45 Lbs.
200 Gallons: 60 Lbs.

Sea-90 Complete Sea Salt is created naturally by lunar and tidal activity. Specifications may vary by tidal season. Always test small batches to meet your operation’s requirements.
