I have this on the end of 100 feet of weighted air line...sitting in the middle the fishing pond on some rural property I own. I just drooped it where I wanted it...could not have been easier. I have a reliable air pump...and now I have a constant 3 foot circle of gurgling bubbles in the middle of my pond...just exactly what I wanted.

Happier fish, less algae acculturation, and muck clearing up. Also purchased weighted airline, pump. Installation very easy, plug and play. Took a dip to hide the line.

I have a pretty small pond, about 20 x 20 feet with the deepest spot about 4ft. My Koi's are having lots and lots of babies and I want to make sure there's plenty of oxygen in the water. I also wanted aeration during the winter so my pond doesn't completely freeze. I've been running an Ecoplus 793 GPH pump with a 6 inch air stone. It's worked great but I wanted something a bit bigger. So I decided to try this Rootscap aerator.First, this thing is big. Much bigger than in the picture. The base is about 5 inches round and almost 3 inches thick. There's a 3/8 barbed connector at the base. Protruding out of the base are 4 13 inch long perforated rubber tubes, about 1.5 inches in diabmeter. Connecting it to the pump is easy, I just used a 3/8 ID sinking tube, connect it to the barbed connector and secure with a hose clampl. Tossed it in and, as advertised, it landed right side up.In use, I'm very happy. The bubbles are a bit larger than an airstone, but still pretty small. Nothing like an open hose. I think there's less resistance as well. I don't have an apple to apple comparison, but looking at the picture below, the large bubble are from the Rootscape. The small are from the airstone. The Rootscap is about 1ft deeper as well in this part of the pond. The pump for the Rootscape is a 1030 GPH pump, the airstone is 793 GPH. The output from the Rootscape is more than what would come out of 4 airstones. There's definitely less flow resistance from the Rootscape due to larger pores.Overall, I like it.3 year update...holding up great. I run these alone with the Matablo round disc aerators....the round disc aerators clog up over time....decreasing air output and putting more work load on the air pump. These don't clog...even when I turn off the air for months...They put out great air all the time. I've replace all my round disc aerators with these and are much happier.

Would not buy another as my current aerators put out as much bubbles as this

I replaced my air stones with this unit. I got so tired of cleaning the air stones every month or 2 and they never really put out enough air. I put this unit in March of last year. It NEVER needs cleaning; the volume of air is 4 or 5 times that of the air stones from the same air pump. There is almost no back pressure! My fish love it, I have a 4,000-gallon koi pond with 8 very large mature Koi, and they swim in and out of the bubbles enjoying the massage. Tests of the pond show more O2 and less nitrates. Note, there are a couple of "look alikes" that are cheaper, but they aren't as well made. A couple of my friends bought them by mistake.

Those aeration "fingers" came off repeatedly. I complained & the company sent me another set. They are flimsy and clogged. I ended up using the base without the aeration tubes. Not worth it. Bought a Matala. Better made better material.

This is the best aerator we have found for our pond. Our pond is small, but very deep and lined with clay. Every other aerator we have tried has gotten clogged with clay after just a few weeks. The design of this device is what makes the difference. It has “fingers” that stand up. Air is diffused through slits in the fingers. This design keeps the diffuser out of the clay. In addition, we mounted it on a semi-flotation plate to compensate for the weight of the aerator. It has been in the water for 4 months and is still working as well as the day it was installed.One year update: This aerator has worked perfectly since the day it was installed. It never needs cleaning. Every other aerator we have tried needs to be pulled up every month or two because they clog up with clay. This product is great. Highly recommended.

This aerator does an amazing job of moving air to create bubbles. I had no idea how my old one was failing until I sat this one in my pond.The catfish, bream and bass are thanking me.
