aquariumstation Aquastation Silent Swirl Controllable Dc Aquarium Pump 60W 2377Gph-Marine Wavemaker Return Pump with Sine Wave Controller for Salt/Freshwater Fish Reef Tank Sump Circulation DC9000

I got this to replace an old A/C sump return pump which produced a loud humming. This one is much better, much quieter. The flow rate is fine - some reviewers have noted that it seems low, but I haven’t found that to be the case. With my 55 gallon aquarium, I have it set at 25% speed so there’s plenty of capacity available.I like the controller too, it is easy to use and the display is easily readable.The build quality seems to be really good.All in all, a really nice product.

Works well

Controller gave an error message and pump quit working within 2 hours. Unable to clear the error message or even find out what the error was. Stick with good brand names.

Ok, so I'm setting up a additional propagation system and am trying to do it on the cheap. I had very mixed thoughts about this pump, especially given the very mixed reviews. Ordered one to test given the price to flow rate. Here's where I'm at.The initial pump I ordered has been running about about a month no issues. I've since ordered two more. All are running and consistent in performance. I am using them in an IN-SUMP configuration so I can't comment as to the leaking issue others are have mentioned but the overall build quality is surprisingly good. If they are leaking I would imagine it would be slow and likely a crushed or out of place gasket imo. (Straight up guessing)Cons: Flow rate is definitely not "as advertised" I'd say best guess 2750GPH full flow rate. They do not handle head pressure well at all. Take at least an 7-10% performance hit for every 1' of head pressure. I think it's related to a slightly undersized propeller design within the housing. The flow rate is pretty consistent but can go through periods of momentary variations. Small, but enough to notice if you're looking for it. The included intake guard is pretty thin and flimsy, it seems to be holding up but I'd expect to see chunks breaking off within the year. I think that's about it on the negative side.Pros: The inclusion of two full sets of multiple fittings is and multiple gaskets is a nice touch. (An extra housing gasket as well would be even nicer...) The wiring and connectors are solid. The controller is small enough and simple enough. Nothing fancy but variable speed with 20 steps in two modes. Makes fine tuning flow easier. Haven't tested and don't care about the variable whatever pressure mode so I can't comment to it's effectiveness I just care about steady flow which this pump achieves. Oh and dead silent operation, like impressively silent. Also the price... Even at the more realistic flow rate, there is nothing I could find that compared to this pump price to performance. Assuming their customer service is as good as others have said in the comments should I run into issues I'm totally sold on these. It's cheaper to just buy an extra to have on hand at all times then to run multiples of any other return pumps I saw. I will of course update this down the road should anything change.

Works great. Easy controls and make no noise. Unbelievable.
