How many gallons are in my pond?
The easiest way to estimate the gallons in a pond is to use the following fomula(s):
For a square pond =
Length x Width X Average Depth x 7.48 = Gallons in pond
For a cicular pond =
Length x Width X Average Depth x 7.48 x .75 = Gallons in pond

What does EPDM stand for?
EPDM stands for the chemical makeup of the rubber;
(Ethylene Propylene Diene Monomer)

What size pump do I need?
You should have a pump that will turn your ponds water over at least once every two hours. If you have a waterfall that requires a lager pump, then you would up size accordingly.

|
If my waterfall is two feet wide. How big of a pump do I need?
For every foot of width in a waterfall, 1000 GPH (gallons per hour) will give you .25 of an inch of water over the spillway.

|
How deep should I make my pond?
For fish, at least 4 feet deep. Healthy fish like to move up and down as well as side to side.
Check your local fence requirements (building codes) and freeze line depth.
For water gardens the pond can be 18" and deeper.

What if I don't want a pond, but want a nice water feature?

Do I need to use Underlayment?
Yes. In order to get the livetime warranty on our liner a 6 oz. geo must be used underneath the liner.

Can I have a water garden and a koi pond?
YES. Koi do not have to be raised in thouroughly clean tanks. They are raised in mud ponds in Japan.

What size pipe should I use for my pump?
.5" pipe < 300 GPH
.75" pipe < 720 GPH
1" pipe < 1,200 GPH
1.25" pipe < 1,600 GPH
1.5" pipe < 2,600 GPH
2" pipe < 4,800 GPH
3" pipe < 9,000 GPH

What is an asynchronous pump?
Asynchronous motors adjust to the electrical current that is given to them. Like a light on a dimmer switch. Apart from the obvious advantage of being able to adjust the pump to suit your requirements, there are a lot of other advantages like:
Power saving
Increase in life span
Less maintenance
Avoiding shock loading
Soft starting
Decrease in in-rush current during starting
Safety
In most of the cases, the variable speed control is achieved by incorporation of external devices like auto-transformers, variable resistors, regulators, Variable frequency drives etc.
