Hi alfa,
Thanks! BTW, same tank maker as yours.
No complaints abt the DARTs. Relatively silent and flowrate abt 5000l/h after considering headloss and friction loss. That's for only 1 pump!
The other will be flowing in at lower rate coz of tee-off to FR and sump so as not to damage the chiller with such high flowrate figure should be arnd 2000l/h.
BTW, how's the Arctica commercial? Thinking of getting it at the end of yr.
Cheers!
Mark
