Bio Pressure Pond Filter, with 13W UV-C Light, 1840 GPH Suitable for Koi Ponds up to 1000 Gallons or Landscape Pools up to 2100 Gallons

Filter works well but UV light does not work. Had to buy a new UV light for my pond.

When my old pond filter bit the dust, this new design became the replacement. What an improvement! In a day and a half it went from murky green to crystal clear! Ran for about a month and even though the indicator hadn't popped, gave it a few twirls, green bilge came out, looking good!! I don't understand the comments about leaks. This unit doesn't leak at all. If it's not put together properly (user error) of course it could leak, but the design installed as intended won't leak. I like all the fitting options too. I'm using 1" corrugated in out lines (that can really move water with a properly sized pump!) And got a 1.25" lie flat hose for the dirty water into the garden. Don't understand why it isn't IPx5 or 6 water resistant (it's for outdoor use, right? And I live in a rainforest!) And they say it can't be covered with anything (I'm using an inverted plastic crate), but other than that nonsense is a fantastic filter and huge improvement in my case - glad my old one died! Very, very well made, definitely to US design standards.

It does what it is supposed to. It does clear the water. But, make sure you never leave a twist in the tube line. I unhooked it and gave it a good scrub, made sure everything was hooked back up. I woke up this morning to an empty pond and dead fish. The "out" line blew off, the pump kept pumping, and it emptied the pond. My own fault, but just a helpful suggestion.

It works well

I've only had it for a short time so I'm not sure but so far so good I'll keep my fingers crossed he did clear the pond so it's very very crystal clear

It seems built well and it filters okay, it’s not great at getting the small algae particles so far. This is the second one I’ve got from Amazon, the first ones UV light worked for about an hour the stopped, I contacted them and swapped it for another setup. The second filter had the exact same issue, I was going to return it and buy a different filter setup but I liked the size and application of this filter, so I ordered a new 13watt replacement UV bulb and a new ballast for the bulb, tried just the bulb and it still didn’t work, changed the ballast and it’s been working fine since then, long story short if your buying this for the UV light feature, save yourself some headache and buy a quality external style.

Great job. In 2 weeks went from green water to clear water. Backed flushed twice and it is remarkable. Hope it makes it through the winter.

I’ll start by saying that I have had this product for about 2 weeks now. It does the job filtering and making the water clean. Durability is lacking though. The morning after trying out the cleaning feature, I woke up to a pond that was nearly half empty. The 2630gph has a cleaning ‘switch’ (that is pumped?) not a crank. This switch remained partially open and slowly drained water all night. The outlet will remain securely closed from now on, making it less convenient. Maybe I’m doing it wrong but it doesn’t seem to clean any of the filter pads anyways. This will not be a repeat purchase.

We have a 6’x 9’ pond with ~12 fish. The water was very hard to keep clear, especially in warmer weather. We tried all kinds of clarifiers and enzymes with little help. After installing this filter, which is fed by a 600gph pump, it cleared the water within a few days. There was no noticeable drop in water rate to the waterfall after the filter.One thing that is not advertised is that there is a compartment in the bottom of the filter full of bio-balls, so this is both a mechanical and biological filter.It seems well made, and was easy to install. I buried most of it into the ground to keep it out of sight. Very happy.

Easy to hook up

Filter is hooked up & doin a great job. Haven’t had to clean my fountain head since I hooked it up last week, normally a daily event.
