Instructions on calculating aeration required for large ponds and lakes

How to Calculate the Proper
Aeration Required
for Your Large Pond or Lake:

Sizing Requirement Guidelines:

CALCULATE LAKE SURFACE AREA
A) Multiply the length of the lake (in feet) by the width of the lake (in feet) to get the square feet of the surface.
Area = L x W

B) Divide the surface area (in square feet) by 43,560 to get the number of surface acres.
SURFACE AREA = NUMBER OF ACRES
43,560

CALCULATE NECESSARY AERATION
Normal aeration requires the displacement of 1 (one) acre foot or 325,900 gallons of water every 24 to 48 hours. This will add a minimum of 3.2 lbs. of oxygen per horsepower per hour. For normal water conditions use a minimum of 1-1/2 HP (one and one half HP) aerator per surface acre. For warmer climates or excessive algae growth use a minimum of one 2 hp aerator per surface acre.

CALCULATE NUMBER OF AERATORS
Number of aerators = Number of acres (rounded upward)
Example: The lake is 220ft. wide x 370 ft. long (220' x 370' = 81,400 sq. ft = 1.87 acres (rounded up to 2 acres).
43,560
Lake requires either:
(2) 1 - 1/2 hp aerators for normal conditions or
(2) 2 hp aerators for warm climates or lakes with a history of high algae problems.

TO MAXIMIZE WATER QUALITY
Begin aeration prior to hot weather and algae build up.
Physically remove or chemically treat excessive algae and sludge prior to aeration. If water quality is compromised (light to moderate algae), aerate 24 hours/day continuously until algae is under control.

For 1/2 acre ponds you can use our Pond Jet aerator or our "Mini" or "Midi" Strata-vators below.

For 1/2 HP to 2 HP Strata-vator models, refered to as our "Mini" and "Midi" Strata-vators (commercial grade) click here.

For 5 HP to 15 HP Strata-vator models, try our "Maxi" Strata-vator, here (commercial grade).
