My tank is 6 ft long 18 inches wide and 16 inches tall.. I’m on my second 200 series Maxspect gyre circulating pump. I ended up adding a circulating pump on the opposite end of my tank because I started seeing a lot of algae where the gyre wasn’t reaching allllll the way down to the other side of my tank and back.. anyway, I liked the slim design of the gyre but they are pretty expensive to mess up and no longer work as fast as my two have. I am now needing suggestions. I need good water movement preferably not so much that all my sands ends up at one end of my tank but moves the water good without it splashing out all over the floor.. should I purchase another gyre and buy two smaller ones or a couple of the other water moving controllers or what would you guys suggest?
