Return Pump Help

You're probably needing on the higher end of 1500-2000 GPH @ 5 or 6 foot head.

1000 GPH for the tank
600 for the chiller
100 each for the reactors.

That's what I was kind of thinking. I have posted a picture so maybe this will help make it easier to calculate head loss.

Yeah don't get caught up in the calculating. It's 6 feet. Trust me.

If you reeeeeeally care about your flow rate (which most dont), get the fancy new flow rate sensors from Neptune.

I have 150 gal dt, 75 gal refugium immediately below and the sump in the basement (actually crawl space under a split level landing - 42" head height). I use a Jecod DCS 9,000 ltr with variable control I have it set on #6 out of 10 levels. It's almost silent. Hopefully, with your calculations, it will be enough.

Given the picture you posted and the description, with 1" pipe, the 45° and 90° elbows, assuming 1 check valve and the ball valves and unions shown, the calculations are pretty close to a maximum flow out the top of 1,070 gallons unless you go with a pressure rated pump.
