Aquascape 75001 Pond Air 4 (Quadruple Outlet Aeration Kit)

I highly recommend this aerator kit. Fancy, the butterfly koi, and her five pond mates would agree. I bought my kit in 2018 and have had to replace just one airstone (bubbler.) They run 24/7. The only drawback is that the motor is a bit loud. You will need a cover to protect the machine from the weather. Mine has a fake rock cover. Peace of mind is more important, knowing my fish have the oxygen they need. You’ll never have to worry if the fish have enough oxygen, which concerns every pond owner. I have a second unit ready when the first one wears eventually wears out. These aerators are worth every cent. I am so glad I bought them.

Prompt delivery. The Aeration kit works very well. Only problem is that the air hoses are not weighted, so the float on the surface. Here's my solution: I used small black 4" electrical cable ties to fasten 5/16 stainless steel nuts to the air tubes. I pulled the ties as tightly as possible, making a small loop in the tie. Then I inserted the tie through the nut. Finally I inserted the end of the tie back through the small loop and wrapped the tie and nut around the air tube. There is enough tension on the air tube that the tie and nut stay in place, but do not impede the flow of air. I spaced the nuts on the air tube about 10" apart. This keeps the air hose on the bottom of my pond. Sounds like a lot of work, but once you get in the flow, it goes on easily. I only attached the nuts to the part of the air hose that would be under water. -Warren Clark, St. Augustine, FL, USA

I purchased 2 of this 4 outlet units for use in my aquaponics greenhouse. My system is smaller scale, and besides producing food, it's used as a relaxation environment next to the 2200 gallon tank that houses my koi.Had been having issues with aeration in the tanks so finally (after literally hours and hours of reading reviews) settled on the 4 outlets air pumps.Opened the packages.. Impressed with how well packed the were and organized in the box.Set the air stones to soaking in a gallon bucket of fresh, clean water. Left 24 hours. Pulled them out, attached the air lines (being careful to follow the flow direction on each line) and put them back in the bucket. Attached them to the air pump itself. Turned it on and immediately saw a profusion of bubbles in the bucket. PERFECT!The pump was SO quiet I couldn't believe it! I left in on to make bubbles in the soaking bucket for about 10 minutes, then turned everything off and placed the stones in my actual fish tank. Plugged the pump back in and it began aerating my fish.10 minutes after setting it up in the actual tank, the pump suddenly became much LOUDER! Still making bubbles, but absolutely no longer "whisper quiet."Trying moving it around gently, figuring something inside was just loose. No good. Still loud. Unplugged it, left it sit a minute, plugged it back in.. Still loud.I purchased this set up for both it performance and the rave reviews about how quiet it is. Greatly impressed with it's air outflow.... Highly disappointed with how loud it is when it's operating.Completely destroys the peaceful ambiance of the greenhouse.I bought the second unit to use as aerators in my dep water float beds. Contemplating not even taking it out of the box out of fear it's going to start the same noise this one is making.Mailing the seller nextUPDATE!Now..... The pump has quieted down to it's original decibel level of barely perceptible.. But an airstone has stopped producing bubbles. Only thing I can think of is the pump was defective to begin with,and whatever was starting to break inside of it that caused so much noise has finished breaking and now I only have airflow through three tones.VERY dissatisfied! :(Update!Amazon worked with me to get the pump replaced ASAP. The replacement pump has now been installed for 48 hours and is working quietly and efficiently. As it is supposed to.As usual.. Amazon stands by it's promises. Love me some Amazon.UPDATE (Latest and last.... :( )Amazon stepped up and replaced one of the original 2 pumps I bought after it quit working properly right after originally installing it.Since then, BOTH the second originally purchased pump AND the one Amazon had sent as a replacement have gone from working well to working noisily to not working properly at all. The second original one went the route of the very first one in a few weeks, ending up with only 2 out of 4 working air stones. Yesterday the one Amazon sent as a replacement began humming very loudly and continued to do so for several hours until it finally quieted down, with again, only 2 of 4 airstones working.VERY discouraged by this experience. I use these to aerate my aquaponic system. They were all installed in the recommended fashion, protected from getting wet, using properly power levels, the whole nine yards.I will never buy anything from this manufacturer again. Poor to none on quality control.Today going into town to just buy a system from a local brick and mortar.

This is just what i have needed for my pond and appears to work well except that one of the filter pads has a blockage and does not work. I tested this by switching it to a line that was definitely working and it was the pad - not the line.The return process was complicated and I did not want to return the entire product as it is working in the pond (installed yesterday) . As an interim solution, I poked some holes in the feed line with a needle but have ordered a new filter replacement for an additional $9.99. The manufacturer says to contact the seller but that seems very difficult on the website. I called Amazon and they were good enough to give me a partial credit so I'm not out any money on this. I will report further as the season and the heat of summer impact the pond but I'm excited for my fish to get more air.update: I love the way the aerator works - when it works. I am now down from four pads working to 1. Going on line to find a new and more reliable source. The big discovery for me with this system that is at least two years old, is that it assists with keeping the pond from freezing in the winter. I run my filter pump and the aerators (with a cover over to block snow but not air) and have not had the inches of ice to deal with despite below zero temps throughout the winter. My pond water is definitely healthier for the fish too.

The media could not be loaded. A very simple setup and great as emergency or backup system. Using this in an emergency pond as we fix the pump system on the large pond. Is happily keeping about 200lb of koi alive. To stop the aerators moving around and to help them sync I did attach small fishing weights to them.

This pump started out fine, but sometime around 2 months of use something in it must have shifted. Now it's incredibly loud compared to before. I knew a mere 30 day warranty was a risk, but for the price I didn't think it would crap out on me this soon.

Oxygen is one of the most important things for the health of a pond and the animals living inside. This aerator works perfectly and efficiently. It is easy to put together. Once you have, you just plug it in and toss it in and you’re done.

I typically wait a few months before doing a review so it can be accurate. I have a huge pond and I bought this to generate more air in the pond for a better environment for my 25 exotic gold fish and 2 koi, It is still running strong, It has become a bit more loud then the first week but nothing too outrageous. All the 4 ports still work just fine and no decrease in bubbles coming out of each port.
