Costway 54W All-in One 660 GPH Pond Filter 9W UV Sterilizer W/Pump Fountain Kits

Works great, cleans the 250 gal tank and easy to clean. I have 2 as it is easier to clean outside of the pond. One I have had for 2 yrs and it still works great. The tank is only 4 ft deep, so I have the nozzles facing sideways. Otherwise it is too powerful and water leaves the tank.

Bought this pump in November of 2024.. didn't run it until spring.. now it running but not pumping??

No more manual cleaning! This pump does all the work. The sterilizer is a bonus. Highly recommend for any pond owner.

Expected more noise but it's barely noticeable. The waterfall effect is beautiful and adjustable.

Handles my medium-sized pond effortlessly. The sterilizer works wonders, and the fountain adds a relaxing vibe.

my pond looks so much better this was it great bye I'm very glad I did it

Customer Service is EXCELLANT!! Had a problem trying to replace the 9 watt bulb and Verona was very helpful. The bottom of the bulb broke off and stayed in the socket. New bulb would not fit because bottom piece was still in the socket. See photo. Hope this will help others if they experience the same problem.

Been using this for months with no issues. It's built well and performs consistently. My pond has never been healthier!

I have bought a few pumps for my pond over the years. This one has great water pressure and cleans much of the algae out. Worth the money!!

660 GPH is more than enough for my pond. The sterilizer keeps algae away, and the fountain jet is a beautiful addition.

Great wire quality very nice fountain great price fast shipping description was on point cleans my 100 gallon pond with ease

I purchased the CUF-6000 unit even though my pond holds only 600 gallons. I admit that I have too many minnows and I\'m using air stones and the CUF-6000 to keep the minnows healthy. I also admit that if there\'s a way to get confused, I can often find it. I\'ve had the 6000 for about two weeks. During the first week I eagerly watched my green pond water for improvement. It did improve. The filter was doing a good job collecting algae. But the improvement stopped after the first week and things started getting worse again. I cleaned the filter assembly and started to see improvement again. But there shouldn\'t have been so many bits of algae in the water. I began to wonder if the UV lamp was working. Cleaning everything out again, I opened the UV canister. This was also when I noticed the window in the filter box that would let you see if the lamp was working. It wasn\'t. Note that the instructions tell you how to open the UV canister, but they don\'t tell you how to remove the bulb. The bulb in the 6000 pulls straight out. I wasn\'t sure until I removed the shield around the socket. That\'s also how I inspected the switch and wiring under the base. The bulb looked okay, and there weren\'t any loose wires, so I wondered what else could go wrong. Below the bulb\'s base was a switch that would only allow the bulb to go on if the UV canister was properly closed. I decided to put two layers of PVC tape over the switch\'s small metal arm to reduce the clearance it senses. Mind you I very carefully made certain that the tape didn\'t touch anything else. It seems to me that this switch and wiring is likely not supposed to get wet. So you don\'t want to get tape on the base above the switch. Also note that if you get carried away fussing with this switch, the lamp might light up even when the UV canister is NOT properly closed. This could be a health risk, unless you make certain that it is properly closed before plugging in the power cord. On the other hand, if you break the switch, the UV lamp will never light up. My UV lamp works now. I am happy. I wasn\'t looking forward to contacting the company for a replacement. Especially since a new bulb would not have fixed my problem. I hope that the UV lamp will kill any algae bits that flow past it. Eventually it should kill all the suspended algae. Overall, I\'m looking forward to being very happy with the CUF-6000. The filter really collects algae in the water, but the algae will flow around the filter if you don\'t clean it periodically. Now that the UV lamp is working, I\'m looking forward to seeing what benefits it and the bio-balls will produce. I\'m not quite as happy with the user\'s manual. Usually you can figure out what the manual is trying to say, but it caused me to experience some uncertainty. Take item 4 on page 02. \"4. Before all parts are installed completely, the equipment can not be plugged in.\" This statement caused me to open the unit to verify that \"all parts\" were indeed installed. They were. I\'ve already mentioned that page 10 could tell you how to remove the UV bulb. The \"TROUBLESHOOTING\" table on page 11 could note that the UV-C lamp won\'t work if the sensor switch can\'t tell if the UV canister is properly closed. This isn\'t actually a user serviceable part, but it can be helped if you understand how it works. I subtracted a star for the less than clear manual and for having to \"repair\" a new product. Perhaps I\'ll rate it 5 stars if it performs as expected.

This pump and filter system have done wonders for my small koi pond, ensuring the water is clear and clean!

It did an amazing job on our little pond!!

I wanted this fountain filter to put in my spare 100 gallon Rubbermaid livestock water tank. I have 20 goldfish in it and it can get dirty and green in a little over a week. This unit keeps the water clear. I can see the bottom of the tank where in the past after 2 weeks or so because of the green algae I couldn\'t see down 12 inches or so. The setup was easy. You have a choice of 3 fountain patterns. Cleaning the filter is no problem. Unplug the unit, dump the water within the fountain off to the side as dirty water will pour out. As others have said, don\'t forget to take the screw out from the bottom side. I would buy this fountain filter again.

It took about 3 days, but working fine now. Water is pretty clear in the fish pond

Fantastic. My outdoor pond has never been so clear!!

Work\'s very well for my 700 gallon Koi pond. Keep water clear so you can see the fish.

The pump and filter are easy to open/clean and work well. The fountain tube is fragile and breaks off easily. Luckily, I had other fountain parts I used to repair it.

Have had a 100 gal outdoor water feature for a year. Despite cleaning the pump filters and replacing all of the water periodically within days the brown algae would make the water absolutely brown. I tried all sorts of chemicals for algae with no results. Could not see any of the rocks, fish, etc. just disgusting brown water. A friend told me I needed a UV light system. Did a lot of research and with some degree of skepticism I bought this pump about 3 months ago. The water was crystal clean within 4 days and has stayed that way ever since. I have used no chemicals since. This device is amazing.
