Fish have an almost endless variety of color, hues and patterns, but ever wonder why fish lose coloration? In this article we discuss some of the main causes of color loss and how to prevent it from happening.

Welcome to Part 3 of this four-part series, Chasing Colors, Not Numbers, where we learn about the latest research about feeding corals and what coral nutrition means for the reef aquarist.

Mirrors? Acclimation boxes? Feeding? How do you deal with tank bullies when introducing a new fish? Here are a few methods we at MD and many aquarists have used to reduce the aggression.

Sometimes owning a larger reef tank is just not in the cards. Well, if you can’t picture not having a reef tank, don’t fold your cards just yet, because nano tanks can be just as fulfilling as a large tank at a fraction of the cost.

Also referred to as the “dirted” style of planted tanks, the Walstad Method is a low-tech method to keeping a thriving aquarium using organic processes of the ecosystem within.

Ocean tides constantly flush the reef, washing away waste and bringing in nutrients, making water flow key in chasing coral growth and color to keep them in peak health.

Corals need the right balance of calcium and alkalinity to build new skeleton and tissue. Many reefers use 2-part solution or calcium reactors, oh but there is another way to dose your system, with kalkwasser.

One of the most abundant elements on earth, silicon in its soluble form (silicate) can contribute to diatom outbreaks. So before it gets out of hand, here is what you need to know about it to gain control.

Evaporation occurs at the surface of the water, lost to the air in the room, but never returns to the aquarium. How does this happen? What are the causes? And how can we control it?

Maintaining calcium and alkalinity levels is important because an imbalance in either one can limit the growth of your corals and make it harder to keep your water chemistry stable. Using kalkwasser solution is a safe way to maintain calcium, alkalinity, and also stabilize pH in reef aquariums. Here’s how to make your own solution.
