SunSunJVP-110 528-GPH Wavemaker Pumps, 2-Pack, Black

These are brilliant mine gave up the ghost so needed some quickly as my aquarium was deteriating rapidly a nemones was not happy and I brought these for a manage and quick fixHowever I have 180 litre aquarium and not overloaded been running approx 6 months so few fish and anemones at moment well they dont blast but my anemones are really happy with them so I'm happy to may purshase 2 more as lovely mild flow glad I had these defiantly recommend

So for the price it's amazing only thing I found is if you turn them off they run in reverse when starting back up... Easy fix just turn them on and off until it spins the right way... Other than that brilliant bit of of kit for 12 pounds for 2

Not very powerful and when switched off for mantance it never worked again. Very disappointing

Good product.

Waste really! Would've brought better quality and got em to fit straight away , after having to wait for adaptors n such to arrive n then cost ends up being the same as better quality ones , now to see how long they last (feel cheap so doubt long)

Have only used 1 so far but had no issues whatsoever and it works fine.

Excellent for the money.Works perfectly fine but don't expect a long life, but when you pay so little you can't expect top quality.

I've only just installed these so know nothing about long term reliability but initial findings were these things are really underpowered for anything larger then a goldfish bowl. They are useful just to focus on dead spots but wouldn't recommend them as your main source of water flow. Would probably be ideal for mixing salt which is what I plan to do with them one I upgrade

After reading a few reviews saying people were getting a few non working ones, or only one of the two worked i was skeptical. But the price is what made me give it a chance.Straight out the box no issue. Plug and play basically. Great flow. Great suction, read people were having trouble with suction. Release the lever, push tight to wet glass, then compress lever while pushing to glass, thing holds true and I've had no issue with it slipping or falling.Overall glad i took the chance considering its a budget friendly power head. Well worth it and they're working well for me. I have both running in a 60G reef tank.

I was soooo surprised to find that such an inexpensive gadget could be so very effective in keeping my 55 gallon aquarium clean. I have 2 very large pleco's that obviously love the food I feed them (Bug Bites Pleco formula) anyway, they defecate long strands of fecal matter and I was scooping twice a day in order of maintaining a clean environment. Also, housed in this aquarium is a very large Oscar. At first I only used 1 of the wave makers and I had it positioned lower down in my aquarium thinking it would help blow the fecal waste up into my 2 filtration pumps. I really didn't see a difference. So, I looked at a few Youtube videos and learned the wave maker was more effective placed higher up in the aquarium, I used both devices and have them located between my 2 filters and approx. 7" from the top. The cord is just the right length. I hope this product proves its longevity. It's quiet and it simply works!!!!

These work great in my 55gallon aquarium. They keep my black sand substrate nice and clean. Customer service was the best I have ever experienced on Amazon. Ordered the two pack, one was missing the plastic o ring, I notified them of the problem Saturday when I received my order, and I received the replacement Sunday afternoon.

A strange phenomenon I noticed is plugging these in/out causes a light on the same circuit to flash (even when not on). Sometimes I'd wake up in the morning to find they were sucking rather than blowing. When blowing properly though, they seem to work well and adds some life to the aquarium..
