Red Sea Reef Foundation Supplement Pack (Ca, Alk, Mg) 250ml - Complete 3-Part Kit for Balanced Coral Growth in Marine & Reef Aquariums

Works well, but there are cheaper alternatives, especially for larger systems.

Love this stuff

The product was intact and worked as advertised, it shipped in a Amazon bag, and got absolutely demolished, the box was in pieces, and the measuring cup was smashed into pieces as well. Somehow, the bottles didn’t break or leak.

I opened the box and only received Magnesium. The Cal and Alk are missing. This is not cool since our corals depend on it. Terrible.

Excelente Producto

Red Sea makes great product. I have been using their additives for some time now and recently purchased a Nano Max. This is what it says it is a Foundation for a reef tank. I have used this many times of there year and always come back to it.

Bad shipping!!Product box came opened and the measuring dose cup was completely brokenHad to keep because we needed the product, but disappointed that we can’t use the cup that came with it!

Coral likes. Make big! Look pretty.
