Customer Reviews for VEVOR Bio Pressure Pond Filter, Up to 2000 Gallons, with 13W UV-C Light, 1840 GPH, Pressurized Biological Pond Filter System Filtration Equipment for Fountain Pool, Koi Fish Aquarium Tank Garden Water
Works great so far. Does anyone know how to tell if you've cranked the cleaning handle enough to get a complete cleaning. Then how many times do you crank it counter clockwise to get everything back to its normal position?
I just crank that handle and wash all the nastiness into a big ol bucket. That goes into the garden. The UV filter has done wonders for my koi pond. Another excellent step of protection for my pond puppies.
We have a 3500+ gallon koi pond. We purchased two of these, two of the 2100 gph pumps and the 24" spillway. Our pond has never been clearer. It is an amazing value for an amazing product. Thank you, Bevor!
Installed this filter on a small pond with a heavy fish load. The water was like pea soup and unless the fish came to the top to feed you would never know they were there. After 3 days the fish were visible and after a week the water was crystal clear and you can see every rock on the bottom of the pond. Didn't even know the goldfish had multiplied.
