Works fine to mix saltwater in an external situation, but shocks me every time I reach in the water so I’m replacing.

I have two of these in a sixty gallon reef. They run a little quieter than previous pumps and cooler. So far so good after a month.

Our 5000 model works great and has lots of power but it has been humming like crazy and can hear it in the next room. Not happy with this aspect.

An ok little pump. I just use it to move around k1 media inside my sump. Be aware that Foster n Smith mistakenly show them at 200mph and 400mph, they are not. Don't get confused, use the chart, that is correct.

I purchased the 400gph pump. I do not like that the flow control is incorporated into the output stem. It makes it difficult to adjust the flow when tubing is attached. If you are not attaching tubing it might work for you. Also, the pump vibrates when it is sitting on something solid (tank bottom). It does not vibrate when suspended in the water.

This pump was great while it lasted. I purchased the 800 model. It was quiet and powerful. The head height was about 3 feet and still delivered a lot of water to my tank from my sump. The suction feet never really suctioned, not a deal breaker. After a few months, i started having troubles with it getting hung up. The motor was starting to die. When removing the cover to check the impeller, the tab snapped off with little force. The housung is very brittle. Now the cover wont secure on, which is ok, as the impeller wont turn without forcing it first. It's exceded its lifespan, time for something new.

This pump has been running outdoors on timer, 12hrs a day for one month, supporting a waterfall water feature. Flow rate is as good as new so far.

This little pump sits low in the sump. Able to keep water levels low due to this feature. Strong little pump too. I use it to filter my gfo. Keeps everything running well. I should get more of my other tanks.
