  • Much better than the round disc aerators
Color: Original White Air Diffuser
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. ... show more

  • A Great Product, But needs to be easier to connect
Color: Original White Air Diffuser
Significantly increased bubbles and oxygen in pond! But needs to be easier to connect. Larger pumps have hose connections of 1/2", 5/8" or 3/4". Not the 3/8" provided on the product. To be mindful of the customer, do one of two things. Add adapters to convert to 3/8" or redesign the connector so that one can adapt to 1/2', 5/8" or 3/4". That is, provide all these sizes and 3/8". Put the smallest size and then add the other sizes progressively, then one can simply cut off un-needed connectors to adapt to the pump outlet size. Simple, and easy to use and wouldn't cost very much to change the design. Be mindful of the customer! ... show more

  • Replaced A Costly Aerator In-Pond System with A Better And Lower Cost Rootscape Aerator System
Color: Original White Air Diffuser
I started to look for a in-pond aerator system to replace my old system that was more costly to replace the needed aerator tubes. I searched and found the Rootscape Aerator system as I had two in my 7,000 gal pond and one in my 1350 gal pond. I first tried the one unit last winter in the small pond and after using for a few months I ordered two for the larger pond. I am happy with the performance over the units I replaced. They were way less expensive to buy and do perform better so far compared to my old system! Rootscape replacement Diffuser Hoses are available on Amazon for one set of four with clamps for around $20.00. Pretty hard to beat. ... show more

  • Really moves a lot of water! Better than the Knockoff.
Color: Original White Air Diffuser
The media could not be loaded. Been using this about a year. It hasn't clogged up or reduced in function. It's turning over a lot of water, a lot a lot. More them any other air stone I've tried. Mine actually couldn't keep itself down but I am using a 1750gph air pump. I put some bolts in concrete in a real short bucket with plastic mesh tube around it to stop the snapping turtles from getting it as other reviews said they might. I'm really happy with it. Check the video. Edit: I tried ordering a similar-looking, but not rootscape, version fo this design. It was not as good by a lot. ... show more

  • Fragile
Color: Original White Air Diffuser
This purchase was a disappointment. The aerator, even though fairly heavy and substantial, is fragile where the individual pieces meet. It lasted in my pond for 30 seconds. The little aerating hoses are attached to the base with tiny and weak zip-ties. One of them came off just by touching it. One of the blue threaded connectors broke off the moment I tossed the aerator into my pond for the first time. The second connector broke off when I pulled the aerator out of my pond (right away because of the first connector). It's all made of plastic, including the hose connector and all threaded parts. Except for the white base, the overall construction is very weak. Overall, it is very expensive for what this is. I'm not sure how one might aerate anything bigger than a koi pond with it. It feels like air pressure needed to move enough air to aerate a pond will destroy this aerator. But I was unable to verify this, because it broke before my air pump could do anything. ... show more
