Vectra M1 GPH Much Lower Than Expected

[Ugin]

This pump is rated at 2000gph. I'm currently only getting 570~gph (filled a 1g jug in 6.31 seconds (60 / 6.31 * 60))

I just setup a 57w UV sterilizer which has around 7' of tubing. The tubing at its highest point is about 1-2' higher than the return pump. I'm no expert on head pressure but i feel like this is extremely low. Any thoughts?

2000Gph is at zero head. As soon as you start adding hose, turns (etc.) that number will drop. I gather the M1 is just for the UV sterilizer?

Every 90-degree turn counts as 1' vertical, and 10' of horizontal counts as 1' vertical.

Yes, it's dedicated for the UV. I'm sure the gph will drop, but from 2000 to 570?

What size tubing? Bends? Pics would help.

As suggested, some pictures showing the entire configuration and tubing would be helpful. The short answer is yes, depending on how you have it setup - you could see that much of a reduction.
