just wondering what the looping of the spaflex up then down is for? is that to prevent back syphoning?
I used 2x wyes on the return as you can see... Since they needed to be pointed upwards and spaflex needs a wide radias to bend on, that is just how it came out... Why is there a problem with it ??
Since this pic was taken before I was completed, There is now a pipe connected to the shut off TUBV that is in the above pic that feeds the 50gal macroalgae tub and if the pump were to lose power (which is on an UPS unit that should last atleast 2hrs) it would suck in air preventing back syphoning of the tank, I have tested the system a few times (with the UPS disabled) and the sump will not overflow...
