FAT CAT™ Aeration System
Continuous aeration benefits your pond in a number of ways: It can reduce or eliminate the need for emergency aeration and water exchange; it can reduce the buildup of ammonia, blue green algae and muck; and it helps to keep oxygen near the bottom, where it can keep benthic organisms alive. The FAT CAT™ is a series of small diffusers attached to one or more floating high volume air lines and driven by a low pressure, low maintenance air blower. It is simple, efficient, inexpensive to purchase and maintain, and has no propellers, paddles or electricity in the water to damage the fish. There are a number of ways to aerate shallow aquaculture ponds but, honestly, we know of no other method that works as well or as cost effectively as the FAT CAT™ for up to one acre ponds.

FAQ
How does the FAT CAT™ system improve water quality in a pond?
The FAT CAT™ system releases air bubbles into the water, promoting oxygen distribution throughout the pond. This helps reduce ammonia buildup, limits blue green algae growth, and prevents muck accumulation by maintaining oxygen levels near the pond bottom.
Can the FAT CAT™ system be used in ponds larger than one acre?

Is the system easy to install and maintain?
Yes, the system is simple to install and requires minimal maintenance. The diffusers are attached to floating air lines and powered by an external air blower with no parts submerged in the water.




Anne Kerr –
Installed the FAT CAT™ system in a 0.75-acre pond last summer. It has significantly reduced algae growth and kept the water clearer. No fish injuries reported, and the setup was straightforward. Works well even during hot summer months when oxygen levels drop.
Nicholas Gill –
The system performs reliably in our shallow pond. Oxygen levels improved noticeably, especially in the deeper areas. We no longer need to do emergency aeration. Easy to maintain and the diffusers don’t interfere with fish behavior.
Megan Wilson –
After switching from a traditional aerator, we noticed less muck and fewer ammonia spikes. The FAT CAT™ is quiet, low-maintenance, and effective. No electricity in the water, which is a big plus for fish health.
