The AquaMaxx Sigma series reactors are an excellent, compact, and unique addition to your reefing dreams. This reactor has some distinct features that make the traditional reactors seem obsolete. For example, you don't have to unscrew thumbscrews which allow for easier maintenance. In addition, their tension-fit lid system allows for easy removal for refilling and dumping out any old media. Finally, the added convenience of twisting off the reactor body from the reactor's base makes maintenance a breeze.
