The Pro UVC with 18w will keep a larger pond clear from free floating algae to prevent green water. The algae is exposed to the uv light killing it and clumping it together making it easy for your filter to trap the larger particles to be digested by the beneficial filter bacteria. The unit is supplied with a multi stepped hose tail or a rigid connector to take 1.5 inch solvent weld pipe. The blagdon pro uv's have a unique expandable system.
