Product description

Product Description Organic Active Salt is a specially developed sea salt made from the highest quality ingredients. Thanks to the additional organic ingredients it contains, this enhances the growth, colourfulness and polyp appearance of corals and is therefore ideal for well-stocked running marine aquariums. Organic Active Salt supports a healthy build-up of the calcareous skeleton and lets even the most sensitive species of corals and fish actively thrive. Directions Follow the safety instructions and instructions for use on the product label.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
