The Role of Magnesium in Marine Aquarium Chemistry

One of the big differences in moving from freshwater systems to saltwater systems is a greater emphasis on water chemistry. There is a pretty steep learning curve to get a handle on all the different chemical parameters, and it can be a source of frustration for many aspiring reef hobbyists.

Why Many Marine Fish Benefit From Mature Tanks

Astute salties out there will likely have observed that in some of our fish species profiles, we emphasize the need to keep the fish in a “mature” aquarium—meaning one that has been set up and established for at least six months or so (not one that has progressed beyond telling horrible knock-knock jokes or taunting … [Read More]

What that usually means is running to the local fish store and frantically scanning the medication aisle for a product that seems to cover the condition in … [Read More]

5 Tips for Maintaining Stable Salinity in a Saltwater Tank

While salinity and other water parameters are relatively constant on the natural coral reefs, they’re highly prone to undesirable fluctuation in the closed system of a marine aquarium. As conscientious hobbyists who want to provide the most naturalistic environment possible for the sensitive fish and invertebrates in our care, one of our primary responsibilities is … [Read More]
