Ok, just got off phone with thepondguy. So my run to my waterfall is almost 20 feet, that's why we went with the pump we did. There is also a ball valve that will be installed before the UV filter (40W) to take the flow down to about 3000 so the UV will work. He told me about quarter of a turn. Does this sound ok? I FEEL like the pump is too strong, but he assured me with the ball valve, uv filter and going through the waterfall that it would be ok.
You missed this info in first post no big deal but thanks for clearing up. 20 feet of head will lower your pressure output and diverting some of the flow to uv will help as well ( we won't start on uv's some swear by them others like myself do not use)
oh btw friendly jab Go Yanks.
