This is how:
University tests have shown that a cubic foot of beads that have 400 - 450 cu. ft. of surface area will handle 50 lbs. of fish being fed 1% body weight per day @ 38% protein.
This is the formula that we use, even though our beads have 500 to 550 sq. ft. of surface area per cu. ft. and in theory should do more, we refuse to stretch or make claims beyond what has truly been tested.
| Model | Size (cu. ft.) | Max Pond Size | Flow Rate (gpm) | Fish Load (lbs.) | Dimensions |
|---|---|---|---|---|---|
| AquaBead 1.75 | 1.75 | 2500 gallons (U.S.) | 50 gpm | 87.5 lbs. | 19" x 31" |
| AquaBead 2.50 | 2.5 | 5,000 gallons (U.S.) | 70 gpm | 125 lbs. | 21" x 32" |
| AquaBead 4.25 | 4.25 | 10,000 gallons (U.S.) | 90 gpm | 225 lbs. | 24.75" x 34" |
| AquaBead 6.0 | 6.0 | 17,000 gallons (U.S.) | 120 gpm | 300 lbs. | 30.5" x 36.75" |
| AquaBead 10.0 | 10.0 | 25,000 gallons (U.S.) | 180 gpm | 500 lbs. | 36 7/8" x 42" |
