Grech CPF-2500 Pond Bio Pressure Filter UVC 13-watt Up to 1600 Gallons with 720GPH Fountain Pump

This pump and filter seem to work well for my smaller pond. Very simple to put together I have not seen any leaks, super easy and simple to clean and the price was much better then the other models. The reason I only have it 4 stars is because I’ve notice after a month or 2 the switch that flips it from filter to backwash it becomes very difficult to switch them back and fourth almost the the point that I’m concerned that one day it might break 🤞🏻 but again for the price it wouldn’t be to much of a problem to just buy another one if that were to happen. Thanks to this filter I can hide it as I buried it 2/3 the way underground and I now with proper maintenance and chemicals have a crystal clear koi pond. Oh last thing it says it has a UV light which I’m sure is what the plug in is used for but it’s hard to tell if it’s on or working or when it might go out but my pond looks good the pump runs well although I added a larger one simply for water flow amount coming down the stream. Overall would recommend for a smaller pond or beginner ponds
