4000 Gallons Pond Pressure Bio Filter with 13W UV Light

Keeps pond clear

This is an excellent filter. Keeps pond clear.

Works like a charm - mostly

I used this for a smaller above ground pond (700 gal) as I wanted more koi than I should, I wanted a bigger filter capacity than I needed. This does the trick. There are some common sense things that need to be learned about gaskets and such but good. The knob on top that compresses the filters while backlashing is difficult to turn and release from the compressed position. but that feature was mostly cosmetic in my evaluation as one has to take it apart and clean off the filters now and then anyway. 9 months and working great.

Working great, clearing pond up nicely.

It is a good filter and I have already recommended it to others.

Works well

The filter works great in collecting algae from my pond. The backwash system doesn’t work for me through the backwash outlet. I use the outlet that goes to my waterfall by switching out existing hose with a 1 1/2” backwash hose for swimming pools. I then use the mechanical pump that flushes the sponges.

New Filter for KOI Pond

Decided to order the filter unit based on research and specifications for our pond. We have been KOI owners for the past 40 plus years and have used primarily Tetra Products which are very costly based on name brand. However, the quality, price and functionality of this filter is excellent. In just 48 hours the water is crystal clear and the Koi are very active (Happy Fish Dance) in the pond.

work great

Pump works great. It takes up very little space.Perfect for engineer designer, I install it for my back yard fish pond ,structure and material very good so I think price is still very cheap. It works well and it's very easy to remove the foam filters and rinse. I do this about once a month.

Keeps water clear

This filter is overkill for my pond, so somebody with the maximum size pond that this supports might not get results as fast as I did, but considering the price, it made sense for me to get even for a smaller pond. I replaced a smaller filter that simply needed cleaning too often. Since the size of the pump depends on the size of the pond, not the size of the filter, this allowed my existing pump to work with less resistance, so I get more water flow.If you have a small pond, I'd definitely recommend it. If you use a smaller pump with a smaller pond, you can expect the filter to work fine, but the indicator might not work if the filter is dirty. That's not the fault of the filter. It would mean that you have enough pressure to keep the pond clean but would have to check the filter manually if it's not filtering as well.

Awesome pond filter

This filter is amazing. Easy to hook up, work brilliantly. I have a 1600 gallon pond with about 18 small to medium size fish and this filter does the job. Highly recommend.

It's a good unit

Pond filter

I followed a video on POND UNBOXING and it was easy to get it up and running.

Can make a small pond crystal clear in just 2 days

I brought this new filter in order to replace my old filter, as it was starting to not work as well anymore. This filter is better than my old filter at cleaning out dirty water. My old filter would take roughly 5 days in order to make my pond crystal clear, but this one only took about two days. Also, this filter allows me to not waste any of the water, whether it be dirty or clean. It can actually spray out the dirty water into another area. This is perfect for the mini garden I’m planning on building next to my pond, as I can divert the dirty water into the mini garden in order to provide nutrients to my plants.

Amazing results cleans quickly.

Awesome filter, I have a small pond and it’s about 1000 gallons. The results are shocking, before I installed this, I could barely see the fish with all the green things floating around. This cleaned it all up in about a week or so. Didn’t take a genius to instal it either, very clear instructions

So far good

Its ok so far but yeah lol leaks

So far so good. Easy to set up and it appears to be mechanically functioning properly, the output hose to my waterfall is very strong. I'll add more pictures as it continues to work but this picture is from the second it installed
