Which pump?
40L - One aeration dome  down to 4 - 6' deep max (Or two 6" Stones)
60L - Two aeration domes down to 4' deep max (Or three 6" Stones) OR one disk down to 6' - 7'
80L - Two aeration domes down to 6' deep max (Or four 6" Stones)
TIP: When attempting to pump air past 8 feet down to as much as 20 feet, consider a rocking piston pump. They perform much better.

Air Stone (AS-6)
· 6" long x 1 1/2" Glass-bonded silica
· 1/2 inch male thread
· Single end entry
. Use 1 - 6" stone for every 20L of aeration

Comes with weighted rock inside
Great for large ponds or small lakes

(Consider 40L to 4-6', 60L 5-7, 80L 4-6' x 2 disks, 

TIP: When locating the air pumps, keep them above the water level to prevent water from back flowing, even if the diffusers have check valves...

TIP: Installing a spring loaded check valve on the air line will greatly reduce the air flow and possibly cause undue wear on the air pump. Not recommended!

TIP: If too much air, consider installing a "T" in the line that has a small ball valve on it to permit bleeding off a little air. (Install close to the air pump above water)

How To build; Into a 1/2" threaded PVC "T", install the (2) 6" Aeration stones using nylon tape on the threads. A barbed fitting is threaded into the third opening of the PVC "T" (Also with nylon tape on the threads.)

Drill small 1/8 inch holes in the 1 1/2" black ABS "T" for (4) black ZIP ties. (Enlarge the Right most image for more detail on holes) The ZIP ties are used to anchor the 1/2" PVC Aeration "T". Another ZIP tie can be used to hold the black air line to the extender pipe.  Bottom Intake holes are 3/4" every 2 inches on the two 12" ABS 1 1/2" pipes w/ capped ends. (Enlarge the center image) WARNING - Zip Ties can have sharp edges at the point they secure. Caution should be used to hide those points to avoid fish scrapping those points that will cause injury.

Transported 39 Koi using a battery operated air pump.

Transported 39 baby Koi in a 30 gallon trash can lined with a new black plastic trash bag using a battery operated air pump and no bio-filter. We traveled 3 days in an RV with the trash can in the shower stall. To help keep some good bacteria, we used the original pond water and covered the water surface with water hyacinth plants. We did do a couple of 20% water changes during the trip to help keep the ammonia levels down and all 39 lived. We traveled 1400 miles this way. (Fish ranged in sizes 2" - 7" and were not fed for three days prior to and during transport.) ~ Bill P.

Could be handy to have when transporting to a local Koi Show...

Battery operated air pumps can be found at your pet store or at West Marine
