This pump was able to pump out plenty of flow with 20' of Head height!Using as main return pump on my 110g Reef. I've previously used a standard Danner/Mag Drive for 5+ years that was extreamly reliable and still working til this day. I wanted something with a controller for feeding time and ability to adjust flow. So far pump has been perfect and I'm happy with the product. Been running 24/7 for two months will update down the road.The build is very clean and looks good in sump. Also the controller looks good with the rest of my controllers. A good way to extend the life of any controller/equipment is if possible don't leave devices under your cabinet or near your sump. They will eventually gather moisture and deteriorate.Great pump small foot print fits my sump great very very very quite the only reason I'm giving it 4 stars is the app sucks and is NOT very user friendly pretty much I should have just bought the non smart version it would have saved me 40 bucks but the pumps its self and controller are great!This thing is powerful and quiet especially for it's size. Stays cool with no vibration.The pump is what is advertised. However, the touchscreen is sensitive and will shut off or go into feed mode. Easy to mount.Very powerful and silent. Love being able to control it using WIFIUsed as a return pump for my Reefer 170. I run it at 49% and it's super quiet. Don't use the app much, but the controller functions wonderfully.***UPDATE***This pump is still running flawlessly and quiet. Highly recommend!!It is an excellent pump, with very good power and silent
