ABBREVIATIONS:

t = teaspoon, T = tablespoon, 3t = 1T, g = gram, G = gallons, L = liter, C = cup,

oz = ounces, sol = solution, ppt = parts/thousand, mg/l = milligrams/liter

POND VOLUME

For a mostly rectangular pond, multiply average pond length X average width X average depth (all in feet) to get total cubic feet of pond volume.

For a round pond, multiply the top diameter X bottom diameter X pond depth (all in feet) by .785 to get total cubic feet of pond volume.

Multiply total cubic feet by 7.48 to get pond gallons.

Each one inch of height in a six foot diameter show tank = 17.5 gallons.

Each one inch of height in an eight foot diameter show tank = 31.33 gallons.

LINER SIZE

Add the maximum length to the depth going down and the depth coming up and add one foot of liner on each end for a safe overhang. MAX L + D + D + 2 = total length.

Add the maximum width to the depth going down and the depth coming up and one foot of liner on each end for a safe overhang. MAX W + D + D + 2 = total width.

CONVERSIONS:

One cubic foot of water = 7.48 gallons                                           One gallon of water = 8.34 pounds.

One ml of water = one gram.                                                             One teaspoon = 4.9 ml.

1 oz. = 29.57 ml.                                                                                  One teaspoon = .1666 oz.

1 oz. = 6 teaspoon                                                                               1 tablespoon  = 3 teaspoon

One cup = 8 oz.                                                                                    0.0038 grams/gallon = 1 ppm.

0.001 g/liter = one ppm.                                                                     Liters X 0.2642 = gallons

pounds X 453.59 = grams                                                                  1 mg/g = 1000 ppm
1 fl. oz./gal = 7490 ppm                                                                     1 fl.oz./100 gal = 75 ppm
1 pt/100 gal = 1 teaspoons/1gal                                                       1 qt/100 gal = 2 tablespoons/1 gal

100.0 ppm = 1:10,000 proportion = 0.01 %.

The air around us is over 20 parts per one hundred (0.20) of oxygen, while water has a much lower oxygen level that goes down as the temperature rises.

40°F (5°C) = 12.8 parts per million (ppm) 0.0000128 oxygen saturation at sea level

60°F (16°C) = 10 ppm oxygen saturation at sea level

80.6°F (27°C) = 8.1 ppm oxygen saturation at sea level

POND RECOMMENDATIONS FOR KOI AND GOLDFISH HEALTH:

Un-ionized ammonia levels should be below 0.1 mg/liter.

Nitrite levels should be below 0.01 mg/L.

Nitrate levels should be below 50 mg/liter.

The salt treatment level normal range is commonly 1-3 parts/thousand (ppt).

An alkalinity level between 80 and 350 mg/liter of CaCO3 is preferred.

A pH of between 6.8 and 8.5 is preferred.

The water temperature should remain between 38° and 82° F.
