FluvalSea SP4 Sump Pump for Freshwater & Saltwater Aquariums, 14337

This pump doesn't mess around. Silent and powerful. Definitely not disappointed. I needed all of the 3400gph this pump claims, and it seem to be very close. Main manifold is 1.5" which is larger than the 1.25" pump fitting, and it tees off to two 3/4" and one 1" output. All 3 are valved back by about half. I'll be adding more tanks and this has plenty of power left for that.

I have a saltwater reef tank and used this as the heart of my system. I read many reviews and its made of a laguna block with a different volute. I am very happy with the pump, It is one of the quietest pumps I have ever heard(or rather didn't) I would have no hisitation putting this pump in a setup where the tank was in a bedroom/living area. Its currently in a fish room where noise doesn't matter, but when I enter the room it is VERY quiet.

Received my pump excited to use it, I get it all hooked up and plugged in and doesn't pump water so I dry test it to see if impeller is spinning it was not. I opened the prop housing to find a broken impeller shaft. It is a good thing I have a back up pump for now for my aquarium.There was significant damage to the pump when received. Doesn't look like a new pump. When I opened it I noticed significant damage to the packaging an nothing in factory bags the cord wasn't even factory packaged. I think I was sent someone else's broken pump or return!

I bought this pump to replace my Jebao DC 12000. The reason I needed to replace my DC pump was because my reef tank was in my bedroom and this DC pump produced a high frequency hum. The higher the power, the louder and higher the frequency. By full power, it was like sleeping next to a full size refrigerator when the cooler was running. I tried padding, even suspending the pump in mid water, nothing worked.I just got this new Fluval pump 2 days ago but right away, it made a big difference! The noise level is so low that it's silent when the cabinet doors are closed. Even when open, it's almost inaudible. It pumps more water than the DC 12000 at its full power. So far, I am very happy with it.However, there are two things you might want to consider-1. It's almost 50% bigger than the Jebao. I had to rearrange my sump to fit it in.2. It doesn't have a filter/strainer cap on the intake. You either leave it open or have to DIY a cover.Edit 1/22/20151.I had to take a star down because once I got used to the initial shock of how much quieter this pump was from the DC 12000, I realized that it also produced a loud hum. Not the high pitch whine like DC 12000 but a low pitch hum. After I accidentally set a rock on top of the pump and enhanced the rubber feet with foam, the pump quieted down a bit. Still audible but now tolerable.2. I went to Homedepot and got a 1-1/4" 90 degree threaded PVC pipe. It screwed on to the intake perfectly. Now I angled the pipe to point down and my sump water level no longer had to be at least 8" high.

This is the 2nd fluval sp6 I am now running on my large aquariums. These pumps are huge but they have to be in order to move such a massive volume of water.This product arrived on time and well packaged. Was easily removed from the box and set up was fairly straight forward and easy also.I don't like that the plug is not grounded but also have never felt any stray voltage from this pump either.As compared to other somewhat similar pumps, this pump uses less electricity and is a better price point along with being much quieter.Overall I would rate the fluval sp6 pump as follows:Shipping speed 8.5/10Packaging 9/10Ease of install 8/10Size 7/10Energy consumption 8.5/10Noise level (quietness) 9/10Flow 9/10Very happy with this product and would definitely order it again if I ever needed another.If you found this review helpful, please click "helpful"

seems to be a well built pump and I am very satisfied with it. That being said I needed a pump that would pump 900gph. According to fluval the sp2 should meet my needs however after reading the reviews I decided to upgrade to the sp4 to insure I was able to reach my 900gph. After testing the sp4 I was only able to move 1200 gph not the rated 1800gph. So glad I went with sp4 not the sp2 as I am sure it would not have done the job

This pump moves quite a bit of water but is not nearly as quiet as people say. Mine makes a very noticeable hum, even on its rubber feet and isolated from the plumbing by a silicone hose. Even louder than a Mag 18. A high quality pump that I would not recommend if you want a quiet solution.

Bought this pump to be used in a sump has amazing water flow and is very quiet. I always buy FLUVAL products as much as possible or aqua clear one in the same. None of the pumps ever give me a hard time and parts are always readily available.
