Calcium Reactors: Advantages & Disadvantages
As calcium supplementation has become more automated, one of the more sophisticated means of achieving the desired goal is the use of the calcium reactor.
Chiller Performance Tips
Chillers play a vital role in temperature regulation in aquariums, particularly in heavily lighted reef systems. These tips will help you decide which chiller is right for you.
Coral Coloration
Corals react to light by adjusting the number of cells responsible for utilizing light, as well as the pigments that provide protection from strong light. What we perceive as color change is in fact the coral's natural response to a light source.
Coral Light Acclimation
Careful light acclimation is often the deciding factor in successful transplants. Without proper light acclimation, corals can bleach, burn, or become severely damaged.
