Hello All,
I have a pool with a SWG and fairly well balanced water , The return eyes have air venturi ports on them that when opened add bubbles to the returned water (not a lot but clearly visible).
I assume the would be deemed a aeration but, is it of any value to my pool to a)keep them open, b)keep them closed or c) open them as required (and when would that be)?
Many Thanks
Tim
