Just have a couple quick questions how long should you wait before cleaning your vortechs like every 2 weeks or longer just curious when you guys are cleaning yours. Also what speeds are you guys running yours at i have a standard 55 gal with 2 vortechs as my main pumps plus my return. My tank houses all sps corals and just wondering what the best speed would be. So if anyone is using the vortechs in there sps system just wondering what speed your keeping it at. Thanks
