Fauna Marin is known for producing products designed for high end reef keepers.  For example, their LPS and Sea Fan foods are perfect if you are into target feeding and non-photosynthetic corals.  Everyone these days is testing for phosphates and it is common knowledge that anything less than a bench colorimeter will not provide accurate results.  However, Fauna Marin also makes their own reference fluid for PO4, and given that, we’re very curious as to what level of accuracy they will be able to reach with this new kit.  Stay tuned to the website for product availability.
