SONGJOY Wave Maker Aquarium Circulation Pump 3170GPH Magnet Base Powerhead for Aquarium Fish Tank Pond with 4.9 ft Power Cord

This works perfectly for my 38 Gallon dome front tank. My Acai Cichlids love to play in the current it creates! Best part is it truly is whisper quiet! I read a couple negative reviews and they are false! I have run the 660 for 4 month straight and never had an issue. I only wish it had an on off switch so I could easily shut it down during feeding time. It tends to push some of the food straight to the opposite side and right into the filters intake. But, it helps circulate the tank and keep everything moving. Very happy purchase over the noisy pump I bought before this and now sit is the closet.****update, I bought the 1320 as well and bought a couple line switches so I could turn them on and off as needed. Works great!

I didn’t actually use it because I was afraid it might break the glass of my tank. The magnet was Extremely strong...way too strong...so strong I seriously worried about it acting so erratically when the magnets got close enough to attract each other. They are so strong that it really hurt me when they snapped together with such force. I’d be careful using this on glass and definitely don’t let kids play with it; no joke, they might lose a finger.Other than that it was here on time and in seemingly good shape, I didn’t even plug it in.

3600GPH is probably not accurate and it may have been estimated under certain conditions, I purchased this for a 100 gal pond which seems to be working and circulating the water good enough. My Kois are not hanging around the water fall to get more air but, where the pumps connect to the suction cups is quite flimsy, I am bolting the suction cup to a board and sitting in on a sender block? and holding it down with a rock. again where the pump connect to the suction cup is quite unstable. I had to add a plastic screen mesh over the intake to keep the floating particles out of ther impeller cavity. for the price, nothing else comes close.

*I am rewriting this review under a year later again* **UPDATE 10-23-2018**The replacement unit that I received from them is doing the exact same thing the first one did. I have to regularly unplug the unit to almost "reset it" because it loses a lot of the flow for some reason. I am tossing this unit and getting something more expensive.Not to mention that the ball joint for moving it is not nearly tight enough so it easily moves with the slightest movement.I initially got a defective item. I posted a review that reflected that.The company contacted me right away and sent me a replacement circulation pump (that came a couple days early) and it works absolutely amazing.The flow is great and the fact that you can adjust the flow direction on each one with the added pieces is really nice.Thanks again SONGJOY for your amazing customer support.

Added to my aquaponic garden pond to keep water circulating for the fish.Works great.I did have one incident where a small fish (minnow sized) somehow got trapped within the impeller housing. The incident caused one of the impellers to come off track/out of the drive shaft slot. It was an easy fix as accessing the impeller area is as simple as "unsnap, reset the drive shaft, snap back together, and voila".For the most part, the housing does a good job of keeping fish out of the impeller housing.

The wave maker is quiet and powerful when it works. Mine failed after a few months: broken impeller shaft. I was provided a replacement after I contacted the seller. However, the replacement did not hold very long. After a few months, it failed again due to the same problem: broken impeller shaft. After examining the unit, it seems to be a design flaw: the impeller shaft is fixed on one end only, and thus the vibration leads to its failure. I searched but could not find replacement impeller shaft. Contacted the seller and inquired whether it sells replacement impeller shaft, but did not receive any response. What a waste to throw away the entire unit due to a failed impeller shaft!

I bought this to help circulate the water in a 150gallon tank, to help with a heating problem. The pump works very well, was easy to install, and keeps the water in my tank nicely circulated. The only minor complaint is that every once in a while, it'll make noise. At first I thought it was air working it's way out of my canister filters, but it was not. I have no idea why it makes this noise, and it's not a major issue, but it can be annoying.

Great product for the money the only problem I have had is after about 3 week I have to replace the suction cup so it dont fall and point down and blow my substrate in my filter like has happened twice maybe 3x other than that still tried and true runs perfectly after about 2-3 years would definitely buy again when needed

Broke after one week

No issues

Magnet attached, that sucker ain't letting go

Bought 2 for my 40 gallon work really good thanks

Very goodStrong waves in my 46 galonCommunity tank
