PF4000 36W Pressure Flo Filter

Bought this to replace another filter that just wasn't working out. The pond was always terribly dirty and green for years using other filters. And now for the first time ever the pond is actually clear.

I was skeptical about buying this filter for our koi pond but knew i needed something. All I can say is WOW.. what a difference - even over night! I clean it out at least once a month (it has 5 sponge filters and 'lava-like' rocks for the bottom. I've had it for about 2 months now, and it's still doing an amazing job! Easy to install, clears the water, design is easy to open & clean.

LOVE this filter!! I’m using it on an indoor crocodilian pond (75 gallons). It’s smaller than a previous brand I had and wayyyyy better!! 0 leaks with this one. Maintenance is as easy as it could be! Just make sure you have a bucket/bowl under the outlet before removing the cap to backwash. But the quick connect adapters are wonderful. LOVE it so much. Water is crystal clear. I’m wanting to get a second one for another setup I have. Only downside was how long it took to arrive. Took like 1-2 months, but it has popped up on Prime now, so should be quicker. Regardless, worth the wait.

Sturdy well priced filter replacing one that lasted eight years

I have used this in my pond all summer..it works great. Water is clear. However, it will nor prevent algae build up

I bought a house with a koi pond, I had no idea how maintain it so I spent two years trying to figure out how to get the water to look crystal clear and nothing worked - I was ready to give up on it so basically this filter was my last hope. When I installed it the water was thick green full of algae and dirt, in three days of having the full filtration on I could already see my fish and about a foot in the water - within two weeks my water was crystal clear and now is pride and joy of my background. This product is absolutely amazing, I had to write a review and tell my story! Oh and the backwash OMG super. Easy, takes me 5 minutes. A must buy!!!!! Buy it, buy it, buy it!!!!

It leaks, I had to rig it up for it not to leak. For paying 200+ on a filter you would think you wouldn’t have to go out of your way to make it work, but yet here we are. If you’re not good at thinking outside the box to get this to work properly I do not recommend.

-Using this on a 5000 gallon pond, medium Fish load, and a lot of water plants, the water is perfectly clear, I'm planing on adding some rocks and other elements to decrease the Gallon amount. -Using a Tetra Pond's 4000gph pump as well. conclusion: I recommend this product. -Cons: the product does't seems strong and durable, I'm handling it with care...

Good product. Ruuning well and easy to keep clean

los productos Laguna son excelentes, tengo años usando estos filtros y bombas, solo tengan en cuenta que este al ser mas pequeño no tiene el espacio que tienen los grandes para la roca de bacteria.

Bien conçu. Solide. Facile à raccorder et déconnecté pour nettoyer.

Works as expected, no issues at all over an entire season.

We are very happy with our purchase! if I had it to do again, maybe I'd go a little bigger. But it has made a very big difference in our pond water. They are a little pricey, so maybe watch for a sale!
