Aerated Bottom Drain
The addition of an aerated bottom drain will increase the effectiveness of the drain tenfold. The rising air column creates a current that pulls water along the bottom of the pond towards the drain. This will increase the reach of the drain along the bottom of the pond to remove even more waste for truly superior water quality. The air diffuser has the bonus of aerating the water as well!!
All the Koi experts agree....no serious koi pond is complete without an Aerated Bottom Drain.
This Aerated Bottom Drain has full 8.5" wide X 6" deep sump with 4-inch slip fitting drain, But best of all, a 14 inch Air Membrane Diffuser Cover. (most sold is 9 in.) 14 inch is 2.42 times larger than 9 inches, do the math. That is 2.42 more air than any other bottom drain.
