I'm looking to get two of these and was wondering if theres a control or something on there to were you can control the power of the flow. I'm looking at getting two to help keep debris off the sand but not sure what size to get. There going in a 150 that has two FX5's. I'm looking at the 1200gph ones but not sure if that would be to much thats why I was wondering if I would be able to turn them down if need be.
Thanks
