Fish Mate Gravity UV and Bio Pond External Filters 24W Replacement Bulb for 4000 GUV
I have used this filter for approximately 2 months. My pond was noticeably cleaner after 4 weeks of use. Due to the number of fish, and a neighbors tree which continually drops debris into my pond, I have to clean both filters on an almost daily basis but because of the ease of access to the filters it only takes minutes to complete the task. I'm very happy with this product.

It seem like the last filter that I had has started coming apart, it might what I am using to keep the algae down.

It took 3 times to get one with the bulb working but the customer service was very good. By the time I got the 3rd one water was green, within 3 weeks water is very clear.

Works great. Easy to install. Killed all algae in a few days. Water has never been so clear. Yes I would recommend this product.
