Review: Amazing that a pump this good can be so cheap. - I used this pump for a very unconventional dual-tank setup. The pump pulls the water out of a 55G African cichlid tank before moving it through a bunch of moving media and up around 7’ to the top of another 40G heavily planted shrimp tank. The plants and shrimp handle all the waste from the cichlids because they will eat everything in their tank. I usually keep the pump at level 10/20, but I love having the ability to adjust the flow in small increments right from the control panel. This thing has been cranking for about 2 years now nonstop and shows no signs of failure. Its also extremely quiet. I withheld my review on this for a long time, because I feel that longevity and reliability are pretty much the most important things. Any pump can shoot a bunch of water for a little while, but 2 years of pumping dirty water with no problems is worthy of a 5 star review.
Review: Worked out of the box, and hasn’t stopped after a week straight. - It’s been running non-stop at full capacity for a little over a week now and still going strong. I’m using it in a small outdoor pond with goldfish and koi that got really icky over the winter. The previous pump I got on desertcart died after 1 day, so I returned that, upgraded to this one. Got it next day, and the icky water is now clear enough to see all of the individual leaves on the bottom that need to be cleared out, as well a clearly being able to count the 25 Goldies and 5 Koi that miraculously all made it through the Long Island winter. I love that it is a 24VDC pump because I can power from a solar-charged battery set; but it still comes with a 120VAC adapter so I was able to test it out before attaching to my DC setup. I have it submerged and can not hear the pump at all, at least not over the trickling water sounds of my temporary ghetto 5gal bucket bio filter. It’s definitely not struggling or getting warm or anything like that, so I expect it to keep going through the summer with my eventual big/waterfall filter system. If it’s going to die. It would probably be in the next couple weeks while it is pumping all the winter muck out, and of course I know desertcart has my back for another 3 weeks, if it does. After that just pumping clean water, so I’m not too worried.

## Questions & Answers

**Q: How do i get a 20mm replacement nozzle for this pump ?**
A: I have been trying to reach this seller for quite some time now without any success.  I have used the email address on the box as well as tried messaging them here.... no luck

**Q: How do i set this product to be on a steady flow. The manual isn't clear.**
A: If you press the mode button it switches between 3 digit numbers starting with a 1 or a 2. anything starting with 1 is steady flow. If you decide to use wave mode though the number preceded by 1 also affects wave mode. The number preceded by 1  appears to affect duration of the pulse where as the number preceded by 2 affects the time between pulses if the fist number is set to high the pump runs continuously regardless because the cycle doesn't end before the second begins. So long story short if I set the first setting to 101-104 then set the second number to 209-210 my tank really rocks and roles. Timing and duration are key to getting a wave going.

**Q: Can I use this pump externally?**
A: Yes and No.  Mine leaked external.  I had to silicone it by unscrewing it and sealing it completely with silicone.  Now it doesn't leak and is external. Caveat Emptor.  But, so far a great pump.

**Q: Is it submsial?**
A: yes, i have 2 of the 18000 models and they are both submerged ...

### ⭐⭐⭐⭐⭐ Quiet, cute and strong
*by M***R on May 5, 2022*

The negatives (only a few but not bad): 1). There should be a 90 degree angle input option that can be screwed on so that it can work in lower water levels. 2). The remote should have an on/off, not just a 10 minute "feed" shutoff option. I ended up buying https://www.amazon.com/gp/product/B01FT4RBBM/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 to turn the pump on and off. 3) One set of plugs is not screw in, and they tend to fall out or get pulled out and of course the pump won't work. 4) I make fountains and I know there are many people who will use these for other than fishtanks. So perhaps the word "FEED" can be replaced by the word "PAUSE" so that people can use it on fountains, in water walls and other places besides fishtanks. As I said, these are mainly all minor... This is a really great pump. The positives: It's great! It's so quiet. Even on the level 20. I like that it goes up 20 levels. Many pumps go up to 3, 5, 10. It pumps the amount that they said it does. I also like that it's white and black, which matches the fountains I produce. The connection design and the pieces that go with them are good, strong and solid. I have tried mostly every pump on Amazon. This is clearly top for me and I plan to buy more. I plan to buy many more.
