Laguna Max-Flo 2000 Electronic Waterfall and Filter Pump for Ponds Up to 4000-Gallon

I have this pump connected to our koi pond to run main pond water through a series of rapids and bog filter replacing the same pump of a smaller capacity. This was a great improvement, and the pump does a great job. It works well on an Alexa controlled outlet to produce great flow for four hours twice a day. I highly recommend this pump.

I purchased this for our duck pond/koi pond that my husband and I made. Everyone knows that ducks are messy creatures and, alongside proper filter media, this filter does the job exceptionally well at keeping the water crystal clear. Highly recommend!

I have been using Laguna pumps in my pond for about 20 years, and I've found them to be reliable. My second pump failed at the end of 2022, so I ordered a new one this week. It arrived damaged - one of the five retaining clips for the cover was broken and the cord was displaced, indicating that the pump had probably been packed badly in the first place. I was able to replace the cover with one from the previous pump.

Do NOT purchase! I put this in my pond yesterday and it worked fine at first. When I woke up today, the pump was not running. I thught the ground fault tripped but no, the pump was dead in the water. Not only that, TWO OF MY FISH WERE DEAD, and the remaining 6 fish were all at the top of the water with their mouths out of the water trying to breathe. They were totally lethargic, not even trying to move away when I got to within inches of them like they normally do. Turns out they were electrocuted! When this pump failed, it was putting an electrical charge into the pond and this causes fish to think they can't breathe underwater. YES, this is a thing, google it: "pond fish electrocuted can't breathe" ("Electrocution can cause fish to die from lack of oxygen because it completely disrupts their brain function, preventing their breathing reflex from working.") Luckily I caught it in time and unplugged it before the rest of my fish were dead. After around 20 minutes, they came back to life and started swimming and breathing normally. But two were dead already before i got there. Something inside the motor of this unit came loose or frayed and caused the unit to become "hot" with electricity. POOR QUALITY, This should NEVER happen with a pond pump! I will be contacting Laguna about this.

This is an exact replacement for the Laguna submersible pump I had for 12 years. Very reliable product . Requires very little maintenance.

The media could not be loaded.  Been using Laguna pumps for over 18 years. I'm impressed with the fact that they can run 24/7 365 days a year. With that said, Laguna itself and this website provided miss information regarding the connectors that come with their pumps. Please watch the video as it will clear up a lot of misconceptions before ordering.

I have been using these pumps 24/7/365 for the past 15 or so years to feed my waterfall in my small pond. It keeps on running even with a frozen pond. The one I recently purchased has a smaller output hookup so it is not interchangeable with my older, larger model of the Laguna pump. It is also very easy to clean.

We had purchased a filter from a dealer - he convinced us to get a smaler pump on it to slow the flow of water so that the UV light could have more affect on the algae. We went with his opinion. Then we discovered that the smaller pump did not have the power to lift the water to the top of the falls.My daughter urged me to go on line. I was shocked to see that the prices were much lower than buying from the dealer we had frequented - and I could scrutinize many products right from the comfort of my home. The pump is fantastic - lifts the water with no problem - and I have seen absolutely no difference in the affectiveness of the UV light. My pond is crstal clear. I use a microbial algae killer when I first open the pond - it knocks the algae back - and the filter with the UV light and the Laguna Max-flo 2900 handle the upkeep.The pump is everything that printed on the web site. Would not hesitate to buy another one. It is efficient, powerful, the price was exellent and it was delivered to my door in a timely fashion. What more could anyone want?

Works nicely!

This pump is the same that we had for 15 years or more. It's easy to clean and works with my 4000 litre pond and waterfall. Has lots of power and I disconnect the filter for the winter but leave the pump running through rain or snow. Very reliable.

Best pump I ever had . Lots of power for my 12 feet fall and make no noise at ALL!

Easy to connect, and the fish are very happyQuick delivery , Powerful, worth every penny

Très bon produit. Je prend cette marque depuis des années.
