Specially formulated for use with reverse osmosis or soft tap water, this advanced marine salt blend is designed to meet the needs of today’s reef hobbyist. Utilizing the same natural sea minerals found in premium sea salts, it features elevated levels of calcium and enhanced buffer capacity to ensure extended availability of these crucial elements, supporting vibrant coral growth without the need for immediate supplementation.
This chemically balanced formula supports the most delicate corals and marine life by reaching a stable, natural pH shortly after mixing. It is free of nitrates and phosphates, making it ideal for maintaining a pristine reef environment. Produced through a small batch process, it guarantees homogeneity and consistency in every mix, ensuring reliable water chemistry for your aquarium.
Corals, calcareous algae, and other invertebrates rely heavily on calcium for building their skeletons and shells. While natural seawater at 35 ppt salinity contains approximately 400 ppm calcium, this formula provides elevated calcium levels—around 450 ppm—at the lower salinities preferred in reef aquariums. Magnesium is also present in optimal concentrations (approximately 1350–1390 ppm), along with a balanced alkalinity (DKH) around 11.5, to support healthy biological processes.
Ideal for reef tanks utilizing mineral-free water, this marine salt blend ensures a stable and nourishing environment for corals and other sensitive marine organisms. Whether you are performing routine maintenance or preparing large water volumes, this product delivers superior quality and consistency to enhance your aquatic ecosystem’s health and vibrancy.

24hr delivery of a pallet, for a complete marine aquarium. And two days before Christmas. No picking errors, best pricing and then great service with hour slot from UPN Pallet Network. Impressive!

Nice searchable website, plenty of stock, reasonably priced next day delivery, well packaged. Slightly more detail would have been nice as I bought 32mm thinking that was the external diameter but I suspect most people buying these items would know that. :)

Such a great service. Bought a fish tank Ciano emotions 150 Pro and it's arrived very well packed just 2 days after purchase. After 2 weeks i had an issue with light power supply which has been replaced straight away after I reported that to customer service. They look afyer customers and always replied very quickly if you have any problem. Strongly recommended!!!
