I have had this lamp installed in my 160 gallon pond for about a month now. I spend two years fighting a losing battle against blue-green algae. I tried everything from chemicals to changing the filter twice daily. Nothing came close to working but after two days of using this uv lamp my pond was noticeably clearer and after a four I could see the bottom. The lamp works well for a pond my size. Other reviewers have noted problems with the fittings. They were a standard 3/4 and I found no problem picking up hose from the garden section of the local Home Depot. For the adapters, if needed, check out the plumbing isle. I would recommend this product to a friend.
