Seachem Vibrant Sea™ Marine Salt 23kg (Makes up to 830L)
If you’re running a marine or reef tank and want consistency, stability, and coral-friendly parameters straight out of the bucket — this salt is seriously hard to beat.
Seachem Vibrant Sea™ is a highly concentrated, premium marine salt mix designed to closely replicate natural seawater, while still being perfectly suited to closed reef aquarium systems. It contains all major, minor, and trace elements, with the added bonus of enhanced potassium levels, which reef tanks absolutely love.
One 23kg bucket makes up to 830L of saltwater, thanks to its anhydrous formulation — meaning there’s no excess moisture, no settling, and no surprises from batch to batch. What you mix today will be the same next month.
