AquascapePond Replacement Aeration Disc 4-inch 75005, Gray

Great - Great product. Have used these in our pond for several years. By the end of the year they are covered with algae but clean up nicely and work well the next season. Have used them for 3 seasons. Just ordered this replacement pod to have on hand in case one of the employed units should fail. I can't afford to be without them. They are a great product and the perfect solution for aerating our pond.

Had to replace 1 aerator after 1 yr and 10 mos. Now it works great again.

Works great in our 11x14 koi pond.

Other reviewers have mildly complained that the discs are not heavy enough to lie flat on the bottom of the pond without flipping over, which I will confirm from my own use of this product. However, I have used this Aquascape product and compatible aeration pump for at least 10 years, and have found it to be very satisfactory for aerating my ponds (2000 gallons and 1500 gallon). Even when the discs flip over, they still aerate the water. The price is reasonable compared to other pump systems; the discs are a vast improvement over the aeration balls which were the original product instead of the discs; and they do the job of keeping the oxygen levels in the water appropriate for the Koi, particularly in warmer weather. I had a disaster in one of my ponds 10 years ago when the heat reached over 108 degrees on six consecutive days, and I did not have an aeration system in place at that time, and I lost many beautiful Koi as a result. For serious Koi hobbyists, protect your fish with an aeration system of some sort to avoid such unfortunate pond crises.

This doesn't get clogged like others. It produced great air and is easy to replace

I put it in the pond and works like a charm

Love it. Easy to install.

Great deal
