Frequently Asked Questions on Kasco Pond Fountains

Should I purchase a decorative fountain, aerating fountain, or plain aerator?

If you are mostly looking at decoration and want the large and impressive displays, then a decorative fountain is your best choice. These go higher and wider than aerating fountains. You gain in display but lose in aeration. Some manufacturers sell fountains that really only decorate. Kasco tries to find an in-between even for their decorative fountains, as they still aerate a lot, just not as much as aerating fountains.  If you only need display, no aeration, may we recommend Scott?

If you want to balance a great deal of aeration with a nice, V-shaped display, then an aerating fountain is the right choice. The aerating fountain aerates much, much more than the decorative, display fountain. But to do high aeration, the display is limited to a V.

If you are ONLY looking for aeration and you couldn’t care less about display, then you ought to purchase an aerator. These just make huge bubbles at the surface. And if your pond is over 8 feet deep, you really ought to look into purchasing a diffuser unit.


Aeration Fights Stratification (Layering) of Ponds

Aeration is needed for fish health. If fish don’t get enoughoxygen, they will die. But even if you don’t have fish, without aeration, pondscreate stratified layers, and the bottom layer is depleted of oxygen. Also, thepond surface can become quite stagnant.

In addition, ponds can become shallower over time from abuildup of muck caused by a lack of oxygen. Plant materials need oxygen tosteadily decompose and if new plant life grows at a rate faster than old plantsdecompose (due to a lack of oxygen), muck accumulates at the bottom of thepond. In addition, this muck sends up gas bubbles which can create a very foulsmell like rotten eggs.


Surface Aeration

The most common type of aeration is surface aeration.Surface aeration is also the pretty kind, that is, the use of fountains.Typically a propeller is found underneath the fountain and this prop agitatesthe water, decreasing stratification. In addition, water is forced into the airso that the pond’s water is always being recirculated.

Bottom Aeration

For very deep ponds (over 8’), bottom aeration isrecommended. Typically an air compressor is located at the shore and a hosecarries the air to a diffuser unit at the bottom of the pond. It is verysimilar to the air bubbles rising from the bottom of an aquarium.  Currently, there are many fairly quiet aircompressors available for sale. They need to be housed to protect from theelements, thus quieting them more.


Combining the Two Kinds of Aeration

If you have a deep pond but still want to see a fountain,you can combine the two types of aerators. The fountain would not need toaerate as much and could focus on beauty. This focus allows for a greater rangeof price as well as dramatic viewpoint.

About Solar Aeration

We get many calls about solar aeration. The goal is toeliminate the necessity of cords going to an electrical junction. While we areentirely sympathetic, these units are typically quite expensive, require abattery bank, and rely on steady sun. Without battery banks, these units don’teven work at night, exactly the time when aeration is most important.

Windmill Aeration


Wind units are pretty to look at, but installation time is lengthy and you need to find the best point to install right off the bat.Moving windmills takes too much time. In addition, these do not turn when thereis no wind, and when there is no wind rippling across the pond surface aerationis necessary, especially during the summer.

How reliable are your $399 fountains?

We have had good luck with our house-brand fountains. The displays are amazing for the price. But these are not as durable as the premium Kasco fountains, and do not provide as much aeration. If your pond water is really mucky, the pumps might clog up, especially if they are stuck at the bottom of a shallow pond.

Frequently Asked Questions on Kasco Lights

Should I purchase Kasco halogen or LED lights?

Though it is up to you, lately we have been favoring LED lights, especially since the newer models are putting out even more light than before.

How many lights should I buy for my fountain?

Kasco recommends a 3-fixture package for 1/2HP-2HP units, and 6-fixture packages for 2HP-7.5HP units. These LED lights come standard with classic white and include yellow, blue, green, and red lenses.

Can I buy my Kasco fountain now and install lights later?

Yes, you can, but it is more difficult if you wait. You will need to bring the fountain back to shore, take it apart, and install the lights. It just takes lots longer to add lights later, but it still can be done. It just takes more time. It is relatively simple, however, to add lights later to the Fountain Tech discount fountain or to a Scott fountain.

Why do you keep upselling Kasco?

Actually, for the pond owner who needs a good, inexpensive fountain, our three Ftech discount fountains work quite well. But if you can afford to spend the money, we really like Kasco because their engineers are consistently concerned with aesthetics, reliability, aquatic life, and energy efficiency. They are so proud of their energy-efficiency that they offer an energy-use calculator on their website. They have several engineers and marine biologists on staff. We just plain trust them.

About Pumps

About Fountain Pumps


The “head” of a pump is an important term to know.Head means the vertical lift from the surface of the water to its outlet. Ifthe surface of your water is five feet below the water feature’s outlet, thenthe pump’s head is five feet.

In most pump manufacturer’s specs, you will find maximumHEAD, along with a Pump Curve. This is the lift from the TOP of water, NOT thebottom of the reservoir, to the reservoir. For example, the Fountain Tech 650has a maximum head of 140”. At zero feet it pumps 780 gallons per hour, at 20”of head it is pumping 680, at 60” it is pumping 580. This “curve” shows howmany gallons per hour the pump is pumping at different water lifts. 


Item Watts Max-Head GPH 20" 40" 60" 80" 100" 120" 140"
FT-650 70 140" 780 680 620 580 460 300 150 0

Make sure the pump you buy will fit dimensionallyinto your fountain’s basin. Many fountains have cutout areas in which a pump isplace.

Some other pumps list liters per hour instead ofGPH. A gallon is 3.8 liters. A Fountain Tech 300 gallon per hour pump islifting over 1100 liters per hour.

It is best to use the widest diameter tubing youcan. For instance, the Fountain Tech 300 pumps about 240 gallons per hour atthree feet when using ¾” TUBING,  butonly 75 gallons per hour at three feet if you use ¼” tubing. Most pumps comewith different adapters to fit different sizes of tubing.

When building a waterfall, the general rule of thumbis to have 100 gallons per hour for every inch of width of the fall. So if yourwaterfall is 5 inches wide and 3 feet tall, you need to be pumping 500 gallonsper hour at 3 feet of head, as a general rule.


Pump Head and How to Read a Pump Label


The head of a pump is an important term to know. “Head”means the vertical lift from the surface of the water to its outlet. Even ifthe pump is placed three feet below the water’s surface, you still measure headfrom the surface of the water. In other words, how HIGH will you be pumpingfrom the surface?

In manufacturers’ pump specifications, you willusually find maximum head as well as a pump curve. The maximum head is thehighest the water can be pushed. The pump curve refers to how many gallons ofwater per hour or per minute a pump is pushing at various heights. For example,the Fountain Tech 650 has a maximum head of 140”. At zero feet it pumps 780gallons per hour at 20” of head (vertical lift) it is pumping 680, at 60” it ispumping 580 gallons per hour.
