Hopefully someone here can help. Here's the situation: Wanting to setup 3 basalt column water features. They are drilled with 1 1/4" holes. They will be attached with 1" ID hoses. The height of the columns will be 2', 3', 3'-4'. I am thinking a 2000GPH pump will be plenty (Looking at the Aquascape aquasurge 2000). I will have the hose coming off the pump and then splitting it into three to go to each pump with valves on each pump. Will the flow from this pump be enough? Depending on the discharge outlet on the pump (some websites says its 1.0" while others shows its 1.5" so not sure yet what size it is) splitting it three ways may slow the water too much? Any help would be appreciated...thanks!
