It's the RD 6.5m3, hottest part was at the top back corner, was around 92F but dropped to 90.8F when I snapped the shot.

I guess that puts your turnover rate at about 15x with the head loss

I believe it's actually just over 10x

Here's the pump curve for the RD 6.5m3 and 8.5m3, some people have asked me about it. Sorry but you'll have to convert
