SPECSTAR Pressurized Biological Pond Filter with 13-watt Light, 1580 GPH Suitable for Koi Ponds up to 800 Gallons or Ornamental Ponds up to 1600 Gallons

This filter did exactly what I needed it to do. My pond was full of algae. I began seeing benefits after 2-3 weeks and it was totally clear after about 1 1/2 months, if that. It has been one of my greatest investments. And the wife doesn't have to keep asking me” when am I going to do something about………”.

Did wonders for my 200 gallon pond. Easy to set up. Great results

The easy cleaning of the system

I have 3 of these filters and they're great. They work well and are easy to clean. Good product for fair price

Easy to order. Description was on point. Delivery was on time.

it's fine, it's a water pump. Big deal.

Works very well and quickly. Pretty time-consuming cleaning the filter and difficult to get it open. I still haven't been able to get the top off, but my pond is super clean.

Looked like a good setup. I wound up going a different route and not using a filter that uses electricity.

I have had trouble with it since the first day. It stops working and I can't find out why. I had one almost just like it and it worked for 3 years . I took the old one out and reconnected the new one just like the old one was. I haven't been able to see the light on since day one. I think something is wrong with the infrared light.

Cheap filter with UV light, UV light stopped working after 3 months, changed bulb and still not working. This is second time getting same one with same problem. Lesson learned.. You get what you pay for... Dont buy cheap.
