Fountain nozzles give life, interest and oxygenation to ponds.
Note that all nozzle types produce splash to some extent and thus should be kept in proportion to pond size. Standard rule for sizinf is: Height of spray (water effect) should be less than the distance from fountain nozzle to the nearest pond edge - so a 2m pond is limited to a 1m fountain spray. Height of spray greater than this will result in more splash , water loss and problems with dampness. Nozzles with sheet effects (Tulip and Waterbell), are easily wind affected and should be used in sheltered areas only.
