Water Garden's range of larger fountain nozzles and spray rings are ideal for larger bodies of water or commercial fountain displays. Whilst creating an attractive aesthetic appearance, fountain and aeration nozzles will also assist in increasing the dissolved oxygen content in a pond or lake and assist in circulating otherwise stagnant water. All of our fountain nozzles are BSP threaded connections (British Standard Pipe Threads) so can easily be coupled to fountain pumps or standard pipe fittings.
