Bottom Drain with Diffuser
This drain works very well in fish and koi ponds as it provides aeration while improving the bottom-cleaning action of the drain. Induced current from rising bubbles draws sediment into the drain. It has a 3/4" FNPT air supply connection and the cfm range is .5 to 1.5. It is an adaptation of our D3 drain.
