To Calculate Liner Length:
L = Max Length + Twice Depth + 3’
To Calculate Liner Width:
W = Max Width + Twice Depth) + 3’
Pond Opening: 10’ Long, 8’ Wide, 2’ Deep:
Calculate Length: 10’ + 2(2’) + 3’ = 17’
Calculate Width: 8’ + 2(2’) + 3’ = 15’
Allow approximately 1.5’ of overlap around the pond’s perimeter. 3’ included in L & W.
Volume For Average Pond:
WIDTH x LENGTH x Depth = Cubic Feet
Cubic Feet x 7.5 = GALLONS
Volume For Circular Pond:
RAD x RAD x 3.14 x DEPTH = Cubic Feet
Cubic Feet x 7.5 = GALLONS
Knowing Gallons Helps With:
EX: 11’ x 16’ x 2’ – 352 Cu. Ft.
352 (cubic feet) x 7.5 gal = 2640 gallons
Estimated gallons doesn’t take rock displacement into consideration. A perfect rectangle pond if estimated to have 2640 gallons, but with gravel one has approx. 900 gallons.
Boulders In Pond: Pond Length x Pond Width ÷ 65 = _______ Tons
Rocks In Pond: Tons Of Boulders x .45 = _______ Tons
Boulders In Stream: Every 10’ = ¾ Ton
Rocks In Stream: Every 10’ Section = ½ Ton
Because rocks vary in size, use these formulas as general guidelines.
Surface of pond is constantly skimmed of floating debris. Gravel Allows For: Colonization of bacteria, hiding man-made items for a natural look & allows you to place water plants.
If average depth is greater than 2’, consider one of the following:
A good rule of thumb is to try to achieve 150 gallons per inch of width.
WEIR WIDTH x 150 GPH – PUMP SIZE*
EX: 36” Weir x 150 GPH = 5400 GPH
Rule Of Thumb:
Reservoir should hold 2 to 3 times amount of water in stream & falls.
Water Volume In Stream Bed:
Stream EX: 3’ Wide x 20’ Long
3’ x 20’ x .33 x 7.5 = 148.5 Gallons
Approximately 150 gallons in stream.
Water In A Pump Vault:
Rule of thumb: 40% Water, 60% Rock
Enjoy A Backyard Waterfall w/o The Pond. Disappearing waterfalls and stream can be any size!
Since there is no standing water at the base, maintenance needs are minimal.

In-line pumps are amongst the most efficient pumps in flow comparison. Ideally used in flooded suction application where pump is located below water level. Can be used as grade level w/ check valve. Avoid placing pump high above grade/pond level. In-line pumps are designed to push water rather than draw water.
Ang. 4” BD = 6’ Sweeping Radius
Aerated bottom drains help increase the effectiveness of a sweeping action
Aeration is critical to the overall health of your fish and pond ecosystem.
Increased Aeration = Increased Turnover = More Effective filtration
Cover pond with leaf netting to keep out leaves and debri and birds of prey. Check your fish carefully for parasites and bacterial infections and take appropriate action before winter close up. Do not let pond freeze solid, always keep a small area open to let the gasses exchange Example ( floating pond heater) or aeration pump with diffuser stone. Do not chop a hole in the ice, because the sound waves can affect your fish health
Temperature of water in pond – When water temperature is above 55f koi will swim and start to feed normal. When temperature falls below 50f koi begin to slow down and hibernate. At this point do not feed. Provide a natural refuge for your pond fish while they are inactive by placing large diameter plastic or terra-cotta pipe 6” wide or more.
Remember shutting down your pond pump and filtration systems in the winter months vary due to what type of pumps external or submersible. Filtration systems also vary to what type of filters whether they are in the ground filters or above ground systems. If your system requires shut down for the winter months, make sure water is drained in plumbing lines and filters and pumps.

In the most general terms, pond algae can be divided into two types: Single Cell & String Algae
Single Cell Algae: Microscopic single cell algae causes pong water to turn a pea soup, green color. They will appear when nutrients, sunlight, and water are present. They are so small that it is not possible to simply “filter” them out of pond water.
Methods of Removal:
String algae often appear in clear pond water. It attaches itself to rock in streambeds and waterfalls. Also to sides of rocks inside pond. Blanketweed is another form of string algae. It rises to the surface of pond during heat of the day and stinks when water cool.
Methods Of Removal:
Aquatic plants are an essential part of ponds & water gardens to balance the ecosystem.
Suggested Plant Coverage: 1/3 to ½ surface area coverage
Increased Plant Load: Yields increased Oxygen (DO) during the day, but too much plant load can cause oxygen deprivation at night. Especially dangerous for ponds w/ high fish & high plant loads.
Low Plant Load: Yield increased nitrated (fertilizer) which increases the likeness for algae.
Marginal (“bog” plants):
General Fish Feeding Tips: Feed only as much food as fish can consume in 5 minutes.
Above 65°: Feed color enhancing & high protein food.
65° & Below: Feed wheat germ food (Spring, Fall, & Winter)
General Pond Tips:
80 °+ - Increase pump circulation OR add air pump
75 °+ - Fertilize aquatic plants 2X per month
70°+ - Add tropical aquatic plants to pond
60°+ - Begin fertilizing aquatic plants
50°+ - Begin using bacteria treatments, Re-pot aquatic plants (Spring)
50°- - Cut back aquatic plants (Fall)
45°+ - Start pumps & filters for season
45°- - Keep opening in ice
