Laguna Max-Flo 600 Waterfall and Filter Pump for Ponds Up to 1200-Gallon

If you purchase a pressure pond filter system I'll be up front with you, these pumps last around 2 years. Because everything just snaps together, replacement is easy. I have two pump filter systems, the traditional skimmer and waterfall system and the pressure pond filtration system. I keep an extra pump for the traditional system so when the pressure system is down, no big deal, the Koi are still being taken care of. I use the pressure system because it has a UV light that kills bacteria and somewhat controls algae blooms.

excellent performance

This is hands down the best pump I have used for my application, which is a notoriously difficult one: ducks. I have two Peking ducks that produce a LOT of waste into the 4' x 4' pond they are in, and this little pump takes on that challenge like a champion. Continues to work regardless of the work load it is exposed to.Maintenance is a breeze, there are four yellow plastic screws that hold the outer shell together (which does a great job of keeping things out of the propeller of the pump). I wish they were made of stainless steel, because I have to be very careful as to not strip them with a metal flat head screwdriver. Regardless, the pump comes out of the shell and separates into several easy-to-clean parts, and is easily reassembled.This pump really does check all the boxes of a great design, minus the shell screws. I would recommend spending the additional money on this pump in order to save the money of replacing the cheaper ones, and fighting with trying to maintain them as well.

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.

Our pond pump recently died out. I was so impressed with this pump year after year, and knew it had lasted a long time. I came back to Amazon to find it in my past orders, and was shocked when saw I purchased it in 2014! This little pump lasted us 10 years with zero problems. I immediately added it to my cart to replace the one that died. I hope it lasts us another 10 years+!

This is my second one first one is still working and has been operating 24/7 over last 12 years. Minor issue caused the new purchase. Being prepared for the winter. My first one is going to get through clean and store for backup. Use on my 900 gallon koi pond. Honestly I wouldn’t consider any other name in pumps

The Laguna 2000 pump came packaged new, yet upon opening it I found broken plastic pieces rattling inside the housing. They were broken plastic housing screws and interior mount posts for the pump. I decided to try the pump and it worked perfect. It was Quiet and Powerful for my pond-waterfall feature. So I zip tied the housing together and because its holding togther good enough, I am keeping it. Seems the breakage was from the package being thrown around.I went with Laguna as I also have a secondary pump which is a Laguna. Less powerful than this 2000 but am very pleased with its performance and efficiency over the last 5 years.Minus 1 star as I received it damaged.

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.
