It is only important that you get the recommended amount of product over the 1,000 sq ft area as described on the product label. In most applications, the product label recommends you use 0.6 - 1.1 fl oz of Cleary Torque Turf and Ornamental Fungicide per 1,000 sq ft area.

If you find you need 2 gallons of water to cover 1,000 sq ft, you should dilute the 0.6-1.1 fl oz of Cleary Torque Turf and Ornamental Fungicide in 2 gallons of water.
