Maxspect Gyres pumps are one of the most innovative pumps on the market. The word "gyre" has an actual dictionary definition of "a spiral or vortex" - it also is not exclusive to any one technology. This is a pretty solid technology as it sucks water from under and above the pump on a pretty broad scale then pumps the water back out through the front. The idea behind that is that the pulling of the water helps to eliminate "dead spots" almost as much as the pushing of the water, so these pumps really are capable of eliminating nearly all dead spots within your aquarium. If we are going for transparency here, however, there are several other brands such as Jebao that use a similar technology to create amazing circulation throughout any aquarium. At AquariumSumps.com we use the Jebao CP-55 Crossflow pumps on a number of coral tanks. One other benefit of the Jebao pumps is they are usually less than half the price.
