Review: Received fresh product - I like Red Sea products and I was happy that this is fresh and does not expire for a couple years!
Review: Great product - I use the foundation supplements for my mixed reef with good results. I prefer this over the foundation A powder since it’s about the same cost per amount of supplement and it’s much easier to use. There is a tingle of brown in the fluid which is normal per Red Sea support.
