I need help on if a Cor 20 is too powerful for my tank

I just plumbed my Reefer 350 (75 gal) to a trigger platinum sump that is running a pentair 25 watt UV sterilizer that runs off the main return. My return comes up and then does a 90 through to back of tank, and then several more 90s until returning to sump and then up to display. I’m running a Neptune flow meter. See pics below.

I currently have a Cor 20 but I’m wondering if I should return it for the 15. I’m worried it will be too powerful. It’s also quite large in the sump. Is the 15 smaller though?

thanks for your help

You can turn it down enough and you'll be fine with that pump. I run a 20 on my 150 at about 80%. If you run at 50% that's 1000gph. Which is about where you want to be. Then go down from there if needed. I run a separate pump for my uv to get the flow down around 150-200 gph.
