Nice pump Doni! I have the ampmaster 3000 on my CL and its very quiet. I dont support it though. When i did it made a noise and i hate noise! so it's floating in the air from the return line. PVC is very strong and it holds it just fine. Im not recomending that to you though since your glass is not as thick as mine and yours wont be plumbed up to a bulk head. I agree with everyone else who said to go high. Only because you can pad it up better then and limit the vibration noise to nothing. I would also have a gate valve on the return line so you can back it down if you need to. Especially since its going into the UV.
