Review: Works Great - We have a large pond , and this aerator makes the water beautifully. The fish are happy
Review: Great product and value - I bought this pump and accessories after researching my best options for the price. I have a small 1/4 acre pond and want some air diffusers for both ends. I purchased this about in February 2020 sometime. I bought a housing to go with it so it was protected from the elements and had electric already out so I was able to plug easily into a timer. Easy to setup, was about 50 yards from the house and never heard it run. Worked great up to a few weeks ago. My house is on the Myakka River in Venice Fl and up to Hurricane Etta (Fall 2020), even though the property flooded it was nothing like the amount of water Etta brought us. To make a long story short, the water ended up being high enough to enter the pump housing ( and the housing was raised, not resting on the ground). I waded thru the water and managed to unplug the pump. Once the water went down, I plugged it in again but found the pump was buzzing and not pushing any air. I contacted the manufacturer in China who responded within 24 hours mostly due to the difference in time. I told them what happened and asked if I could ship it off to have fixed. It wasn't their fault and I was happy to pay for the repair if reasonable. I was informed it could not be repaired but they would be happy to replace it (a new model by the way) at an extremely fair price including shipping from China. I took advantage of the price and their service and within about a week I have my new pump and it is working great. They also sent me 2 new 100 ft airline hoses at no additional cost to me which I did not need and am trying to return. In my opinion, great product and great customer service. The pump is easily well built and I have no doubt will last a long time. The airline hoses are thick rather than flimsy and the diffusers themselves heavy and well built too. It's obvious the company stands behind their product and I would definitely purchase this again if I had too.

## Questions & Answers

**Q: What pond size and depth can this system handle?**
A: The HQUA PAS20 system is ideal for ponds up to 3 acres in surface area and 65 feet deep. For best results, choose a system slightly larger than your pond size to ensure full aeration coverage and maximum oxygen circulation.

**Q: What’s included in the package?**
A: Each kit includes a ¾ HP air pump, two 100 ft self-sinking air hoses (5/16" ID, 5/8" OD), and two 10" EPDM diffuser discs mounted on 12" coated steel bases. Everything you need for setup is included — no extra fittings required.

**Q: What’s the best working environment to help the air pump run safely and last longer?**
A: For reliable use, add ventilation. In open areas, use a 6" 10 W fan when over 80 °F / 26 °C. In cabinets, add two 6"–10" vents with filters and a 6" 34 W fan when over 50 °F / 10 °C. For best results, use the HQUA ASC01 housing.

**Q: How loud is the system when running?**
A: The air pump operates quietly at around 50-60 dB, similar to normal conversation. Rubber feet and internal shock absorbers reduce vibration noise. For ultra-quiet performance, install it inside a ventilated cabinet or shed.

**Q: What are the power requirements?**
A: It runs on 110–120 V AC / 60 Hz, drawing about 550 W (6 A). A grounded outdoor outlet is recommended. Use a heavy-duty extension cord rated for outdoor use and sufficient current if the power source is far from the pond.

### ⭐⭐⭐⭐⭐ Pump Still works Great after 2.5 Years (including one rebuild)!
*by C***C on 18 December 2024*

The PAS20 Pond Pump works great and helps keep the fish active and plays an important role helping to control algae. I set up a 90-minute ON/30-minutes OFF automatic cycle on a timer (bought separately). Customer service is Excellent! These are my recommendations (and I will follow-up with my pump rebuild experience): 1. If you like the pump performance, I recommend buying a Pump Rebuild kit (for your pump model year) in advance, so you won't forget. 2. If you plan to rebuild the pump, I recommend taking several photos of the pump before & during the rebuild process so you remember how to re-assemble the pump. 3. If you plan to rebuild the pump (~$50 rebuild vs ~$600 pump), I recommend buying spare screws ($10 for 25 screws M6-1.0x14mm FLAT Head screws). 4. I recommend red loctite to imitate the manufacturers decision ensure the piston stays tight when it gets hot. 5. Removing the 12 screws is easy, but you may need a socket wrench for leverage instead of a tiny allen wrench. 6. The piston screw removal (1 screw per piston) was the most difficult task, and I found a quick solution. The two (2) Flat Head piston screws are installed with permanent red loctite, so I simply used a #2 screw extractor (drilling a hole into the socket, and using an extractor to remove the screw), which is a predictable process for me. (I had unsuccessfully tried a propane torch to soften the red loctite, so I will use to use screw extractors in the future). 7. The piston seal installation was tricky. The seal fits between two pieces of the piston head, and fits tightly within the piston ring (the seal tends to twist out of position). I decided to place the piston in the highest position, fit the ring, then rest the seal & piston cap on the top of the piston-ring. Then I used the screw (adding red loctite) to uniformly press the seal into the piston. This is my rebuild story to help you: As advertised, I followed their instructions exactly (including an automatic on-off timer to prevent overheating), and the pump worked maintenance-free for more than 2 years. After about 27 months, the pump became significantly louder but the pump was making bubbles (in hindsight, this louder noise was evidence of the seals degrading, and the pumping power was significantly diminished). I recommend preparing the Pump-Rebuild process quickly after the pump gets louder (AFTER 2 years). I bought the PAS20 rebuild kit in advance (and make sure you get the kit compatible with your pump model year). Eventually, our pump stopped making bubbles, so I successfully rebuilt the pump. After trial & error, I developed the recommendations above (I had to buy screws in the middle of the rebuild process). In the future, I think I could rebuild the pump within about 3 hours (I consider myself to have average DIY skills).
