Aquascape95053 UltraKlean 2000 Gallon Biological Pressure Filter with 14 Watt UV Clarifier Sterilizer for Pond Water Feature, 2,700 GPH Black

If you've got a koi pond that's dirty & green & you can't see your fish , buy this filtration system. I've got a 2000 gallon koi pond with 15 fish over 18" long & the water was green & full of small particles that my current system couldn't clean. After only 3 days of running the new system with the UV light, it's as clear as drinking water & I can once again enjoy my pond. The product is a bit pricy , but worth every penny. I strongly recommend buying this if you're having water issues with your pond. 5/5

I moved my pond to a new house after 16 years. I have never fought so hard with the weather to keep my pond clear. As a matter of fact, I lost the battle and my pond turned into pea soup. It has full sun, it has downpoured a lot this year, and temp in the 90's for most of the season. I used bacteria, algae killer, and did daily foam filter cleanings. Nothing worked. I bought this foam filter less UV filter and was sincerely skeptical. I did a quarter water change just to give the filter a chance. The water was still pea soup after the change but I hooked up the new filter and hoped for the best. I have not used any algae remover since hooking up the new UV filter. After a week it was grayish murky. A few days later I could see all of my fish strait to the bottom. Now i just have to work on the sediment layer on the very bottom with some organic digester. I will NEVER go back to foam filters and will ALWAYS be using UV from now on. It literally takes less than 5 minutes to clean, has an indicator light that says when it's dirty, and you don't even open the filter to clean it. I have only had to use the backwash 1 time in 20 days. Love this filter and would Recommended it to everyone.

Easy to set up and run. Just two problems. It doesn’t kill the algae and it doesn’t clean the pond. I have a 600 gallon pond with no fish nor anything else. Just water.

A friend of ours who works for a local high end company that creates ponds and water gardens recommended this filter to us. We have been very happy with. It cleared the pond without having to flush it hardly at all. It worked a little slower than oir last filter but is totally woth it since it is so low maintenance. It really does a great jobI gave it a 4 star rating only because the UV clarification stopped working after only a month. We had to contact the manufacturer but they sent out a new balast part within a day and now it is working fine again. Aquascape was responsive and easy to work with since we were still within the 1 yr warranty. It made us a little nervous that the filter stopped working so soon though. We're wondering if there is a defect with this model. But so far the new part solved the problem and hopefully it will not fail again.

I've had it set up about a 1.5 to 2 months. Running in my 3500-4000 gallon pool pond. Took it a few weeks but the filtration and uv caught up with the green alge and now it's crystal clear water. Easy to clean with its backflow flushing, I just use to water the yard a bit till it's clear.Update. Bought 5/16/22 worked well till a week or 2 ago. I noticed eater clarity dropping. Thought with the summer heat I just had to step it back to 24 uv from trying to back it down to 12 hrs. Upon further inspection the UVisnt working any more not sureif it's bulbous transformer. Will investigate further in the morning, but I shouldn't be losing a bulb in 3 months or less

Im giving this unit a 3 star rating until I get resolution of our UV Light failure. I will change the rating if it is resolved properly. We bought the unit March 21, 2025 (Less than two months ago) and it performed fine for several weeks. We saw an improvement in our pond clarity, but a few days ago I noticed the UV Light function was not working. I went through the trouble shooting and it did not change. I have emailed the manufacturer and am awaiting response.I will update upon resolution of our issue.

I am beyond impressed with this filter! I have had my pond 15 years and had many filters that cost more and worked less. My pond is in full sun and usually gets pretty green over the summer. This year I also had more muck in it than I wanted. I purchased this filter on the recommendation of my local pond shop. Set up was SUPER easy, the hardest part was getting the hoses on, I used a hair dryer to warm the hose and it worked great. In just 5 days my pond went from cloudy and green to absolutely crystal clear. Before the new filter I could only see my fish at feeding time, now I can see them even at night. I have a huge black Koi and I can see every inch of him even in detail. This week the little cleaning reminder light came on so I figured I would give the back flow option a try and WOW was it easy. It took me less than five minutes from start to finish and the water started flowing crystal clear again. This made maintenance so easy I am thinking about getting the smaller unit for an above ground pond! Buy it you will NOT regret it!

Had my Koi pond in for years. Always struggled with algae and green cloudiness. Purchased this product a little over a month ago and it is amazing. My pond water cleared dramatically and continues to clear. I can now see all my Koi and enjoy their antics. I purchased the 2000 gallon filter oversizing a bit. My pond is roughly 1400 gallons. This product is worth the cost. Cleaning is a breeze. I hooked up backflow tubing and ran an electrical outlet with a connected on/off switch adjacent to the filter. Now when it's time to clean the filter I turn off the power switch, turn the filter knob to clean, open the backflow valve, turn the power back on for 5 minutes and the system backwashes itself. Would truly recommend this product.
