Abstract
A pipe 35, Fig. 3 (not shown), delivering water to the top of an aquarium has a hole near its delivery end and an open-ended stainless steel capillary tube extends from above the water level in the aquarium into the hole. The flow of water sucks air through the capillary tube into the water.
