Review: Effective, good water clarity and easy to install. - A straight swap for the more expensive Blagdon branded bulb. Easily fitted and effective. I haven't had it fitted long enough to comment on it's longevity but efficacy is okay. The water has cleared to a level that exceeds my expectations. At this price I can exchange them more frequently if required and still be cost effective.
