The Cargill LiquaLife� Hatchery Program
How to Use Cargill LiquaLife�: estimating amount needed.
a.) |
Using the Cargill LiquaLife� Hatchery Program Feeding Table, determine the total amount of LiquaLife needed per tank until harvest. |
|
|
b.) |
Convert liters/tank to kg/tank (x 1.1). |
Note: the density of LiquaLife is approx. 1.1 g/mL (1.1 Kg/L) | |
|
|
c.) |
Multiply this quantity by the number of tanks in your hatchery. |
|
|
d.) |
Calculate how many cases of LiquaLife you will need to order in either type of packaging: |
Cargill LiquaLife Packaging Options
- 1-kg pouches, 12 ct. case (12 kg case wt.)
- 4.5-kg bottles, 6 ct. case (27 kg case wt.)
- 12-kg bottles, 2 ct. case (24 kg case wt.)
