About The Manufacturer
Maxspect is an aquarium equipment company founded in 2009. A group of reef-keeping friends, tired of old-fashioned reef lighting set out to bring modern LED technology to the aquarium scene. They designed and built an LED aquarium light to prove the technology could support coral growth. Today Maxspect is a world leader in slim LED reef lighting fixtures. Maxspects’s mounting systems are simple and adaptable to any aquarium. The company is best-known for their gyre water movement pumps that simulate tide and wave patterns like those on natural tropical reefs. Gyre water flow ensures all of the water in your aquarium is circulating from top to bottom with no dead spots. The Maxspect gyre pumps use magnetic mounts for easy installation. The water flow pattern is set and managed by an advanced external controller.
