This product should be standard in every aquarium. Does an excellent job skimming the surface of the water and will completely prevent biofilm buildup in planted tanks with CO2. I have mine connected to a smart plug, so it is simple to shut off for feeding time and then resume afterwards.

I was looking for a great surface skimmer and i seen this on Youtube and i couldn't believe chewy had it. This is buy far the best surface skimmer ever. I modified one of them for my smaller fishes in one of my tanks. I did it to keep smaller fish and fries not to get sucked up but this skimmer. But other thank that greeaaaat skimmer. I have the 350 & the 650.

I love this skimmer. It can by a little sinsitive about water level but you will get accustomed to it. But what up with the power cord placement. It is seriously in a bad spot. I cut the retainer bracket off mine on day 2 and now its perfect.
