Our Dark Non-Kink Hose has a smooth inside wall allowing for maximum flow. It virtually disappears under water due to its dark colour, unlike clear hose that quickly turns white and stands out against dark pond bottoms. This hose is very hard to crush or kink even on tight bends. Will not grow flow restricting algae inside of hose like clear tubing does.
The following table should be used to size hose for all pond pumps REGARDLESS OF THE OUTPUT SIZE OF THE PUMP USED. If using long lengths of hose or multiple 90 degree elbows a larger hose size is stongly suggested for maximum flow
