Our small pool has 6 return jets which provide great water circulation. However, the way they are positioned they do break the surface quite a bit and I'd like to adjust them lower so as to not add to the PH rising all the time.
I tried to turn the return nozzles (or whatever they're called), but I can't get a good enough grip on them to make them turn any. What is the best way to adjust these? a wrench maybe?
Also, they look like they each have a fixed position, so to turn them lower may change the direction of the water flow, is that normal?
