HAPPYGRILL 2642 GPH Pond Filter with 13W UV-C Light & Bio Balls, 4 Adapters

Works great and easy to set up/use. Water got a tad cloudy after a few days of heavy rain but this guy cleared it up in no time.

Cleared up my 1100 gallon Kio pond in just a few days, Crystal clear in about 3 days. Haven't had to clean it yet, but its been going strong for a few weeks and is very quiet and appears to be do an excellent job! Wish I had a few more for my other projects

On my second one in 15 years. Best bang for buck that I’ve come across. Ofcourse, you have to buy what fits your needs.

I have 3 of these filters for my koi pond. They have done wonders for the water quality. One of the newest filters had an issue. The head clamp plastic split and the filter began to leak. So I bought a different filter like the mercury filter, It's good but I like the one I just bought. These filters are easy to install and maintain. I have one that's 4 years old that I replaced he sponge filters and UV bulb in and even that was easy!

The superior quality and design of this filter was evident when I removed it from the packaging. As I read the instructions and familiarized myself with the product, manual, features and their locations for proper installation and use, I knew it would provide better filtration than even the most expensive filters that I have previously purchased. It has numerous layers of filter pads, and bioballs, backwash option, and UV light with a sensor to prevent overheating The plastic shell is thicker to prevent warping and leakage. It has a lid that is easy to remove as well as an easy to turn dial for for backwashing in between full cleanings and prior to resuming water flow into the pond to remove waste that rises to the top after even briefly removing power. I built the pond and estimate it to be approx 3000 Gallons. Due to my last filter’s subpar performance and a minor shipping delay for this one, I lost 3 of my 14-18 inch Japanese butterfly koi that I have had for almost 8 years. Once I hooked up this filter and completed two 1/3 partial water replacements in two days the water clarity improved and I was able to identify appearance, symptoms, that it was bacterial infection, and then treat my 8 survivors. It has only been a few weeks since and the filter still exceeding my expectations and without cutting the pipes to increase water flow. Aside from the minor 1 day delivery delay, I am happy and considering buying a second one to use for my smaller waterfall. So far, I would definitely recommend.

The backflush leaked constantly, the push button to spin the backflush spit water everytime I pumped it. The UV light shorted out and could not be replaced. I ended up having to completely cap off the backflush and unplug the unit. It's just an overpriced sponge filter that I now have to completely disassemble to clean. Definitely not worth the money I paid for it.

Our pond is establishing itself nicely. The water is clear and the fish are happy

After a month of use, seems fine. As advertised. It is easy to clean.

Excellent customer service and product. Cleaned out our algae infested pond so quickly. Would recommend to everyone, and will be purchasing from them again in the future!

J’ai vue une bonne différence 7 jours après l’installation
