Customers are mixed about the bubbles. Some mention that it does a good job producing good bubbles and a nice amount of skimmate, while others say that it continues to put micro bubbles all in their tank after almost two years. The venturi is so powerful it creates microbubbles that seep through the joints and get in the tank unless you clean them.

"...Well made, quiet, no bubbles getting into main tank, nice design. I would certainly recommend to anyone building a sump for a tank my size." Read more

"...Can position pump inlet to side or directly opposite exhaust. Some micro bubbles but its new and to be expected, it usually subsides once skimmer..." Read more

"So let me be clear: I love the skimmer. It does a good job, produces good bubbles and a nice amount of skimmate and it's footprint is nice and..." Read more

"...Just after 3 full days, it seems it has broken in and is producing foamy skimmate. I will provide update after a couple months of running." Read more

Works as Should
4 Stars
Works as Should
Straight out of the box zero problems. I took off 1 star due to I had to watch a how to put together on YouTube because the instructions weren't very helpful for someone putting a skimmer like this together for the first time. I have this on a 30gallon with a 20gallon sump. I'd probably buy another one.

Skimmer is awesome. Been running for about 12 hours and already has a nice green sludge collecting in the cup. I’m
Assuming I’ll be fine tuning it for a couple days or so, but that is to be expected. Instructions are pretty minimal but enough to provide assistance. Seems to be made of good material, and I hope it lasts a while. I had pretty clear water in my 55 gallon marine tank before I installed the skimmer in my 13 gallon sump, but i have honestly seen better water quality after the installation. I didn’t think the water could get any clearer or cleaner, but I’m a big fan so far. Was choosing between the RO 110, and this one, and although I’ve never used a RO, I’m glad I got this one. The only time I can actually hear it running is when I’m close enough to it to empty the cup. Zero noise added to my setup, only thing I can hear is the light trickle of my overflow box. Very happy with the purchase.

5.0 out of 5 stars Update: Perfect for a 65 gallon tank.
Reviewed in the United States on July 11, 2020
<UPDATE> So I've been running this skimmer for 6 months now and it is gong strong. It skins perfectly, only one problem to report. The o ring at the turn handle snapped in half but lucky I had a couple little o rings on hand. It was an easy fix. I currently have 6 fish in the tank and fed them twice a day and it has done its job. I would definitely recommend to a friend.

I went through a few protein skimmers trying to find the perfect one for my tank size and bio load. This one worked out perfect! I have a 65 gallon tank with a 30 gallon stump and it fits perfectly. Everything i found and tried are always rated 75 gallons heavy bio load and they never got the bubbles up to the cup. This one however, is perfect for the tank size. It skims wonderfully and the space is perfect. It doesn't make much of a footprint. I'm really happy with it. I'm writing this review after a week of running.
