Article by: Brett Fogle

For many people, it's never been a question of whether to use a submersible pump , Floribunda Rose 'Julia Child' vs. an external pump , Vegetable Gardening because most people have smaller ponds , Re-Potting Your Orchids and are used to just using a submersible pump. , Gardening Tools - An Overview They're easy to install, and are pretty reliable - so why even consider an external pump?

There are a couple of reasons...

But before we go into that, let's briefly talk about the benefits of submersible pumps , Everybody Feng Shui Tonight - in the Garden first. For obvious reasons, a submersible pump is named as such because it is designed to be placed in the pond, and submerged under the water. , Floribunda Rose 'Julia Child'

These are the easiest of all pumps , Growing Palms to install, just drop them in the water , Tips For Cleaning Your Patio and plug them in - and you're ready to do. Of course, you might have some quick plumbing , Six Good Reasons For Going Organic to do, attaching a hose to the waterfall or to a submersible filter (another article entirely), but other than that - that's pretty much all there is to it.

Submersible pumps , Gardening Tools - An Overview range in size or gallons per hour, from 50 GPH all the way up to 50,000 gallons per hour, but for most ponds , Some Great Ideas for Spring Patio Furniture - pumps anywhere from 350 GPH to 4000 GPH will do just fine...

So why might you also consider an external pump , What's In Your Yard instead?

Here are a couple reasons. First, external pumps , Floribunda Rose 'Julia Child' can much more energy efficient. Now, a typical swimming pool or spa pump , Growing Palms won't usually fall , Saving Seeds from Your Garden into this category - so be careful not to compare apples to oranges! Pool pumps , Hills and Holes: Not Part of Your Landscaping Design? can also be huge energy , A Rather Shady Affair hogs, so always check the amps to compare different pumps , How to Grow African Violets together. Anything over 10 amps will draw a significant amount of $$ out of your pocket every month in electrical costs.

The external pumps , Saving Seeds from Your Garden that we are talking about are designed specifically for ponds , Garden Shed - Using It as a Workshop or Craft Room and water gardens, , Soil, Drainage, and Water and are engineered for energy efficiency. I'm not sure why those folks in the swimming pool and spa industry haven't figured out how to , A Rather Shady Affair this yet, but I'm sure they'll catch on sooner or later.

I'm inclined to think the average pond , How Do I Keep My From Turning Green? owner is a bit more intelligent than the average pool owner. Why else would someone choose a pool over a pond? Unless of course you have both, but at any rate - let's just assume that we're talking about external pond pumps , Foraging In The Forest: Finding Materials That Link Your Home To The Great Outdoors here.

For comparison, a typical 4000 GPH (gallons per hour) submersible pond pump , Mosquito Disease will typically draw anywhere from 10 amps all the way up to 15 amps, depending on the brand. This can really burn a hole in your wallet (or pocketbook) on a monthly basis, and in some parts of the country will run you $50 - $70 in energy , Boundaries and Rooms in Your Garden costs.

In contrast, a comparatively rated external pond , Everybody Feng Shui Tonight - in the Garden pump like the William Lim Wave I External Pump (https://www.macarthurwatergardens.com/Pumps/wave_pump_for_ponds.htm) is rated at 4380 GPH at 3.47 feet of head, and only draws 2.3 amps - that's 3/4 less energy , How to Naturally Dry Hydrangeas consumption than the submersible pumps.

When you start getting into larger ponds, , Container GardeningTips 1000 gallons up to 20,000 and above - it's usually a good idea to look into these more energy , Want to Build a Pond? efficient pumps. , Why Gardening is Better For example, the 3/4 HP Dragon pump (https://www.macarthurwatergardens.com/Pumps/dragon_pumps.html) will move 7,770 GPH at almost 5 feet of head (and under pressure) and only burn 6.2 amps.

External pumps , Weed Control Facts - Winning the Battle of the Weeds are almost always better for using with pressurized external filters as well, as submersible pumps , Feng Shui in the Garden are not designed to handle all the back pressure. Other benefits of using an external pump , Garden Room Basics include:

-> Easy to clean without getting your hands messy

-> Easy to hook up to bottom drains or surface skimmers

For smaller ponds, , Rugged Outdoor Elegance: All Weather Indoor / Outdoor Rugs and for simple installation and daily use, submersible pumps , Weed Control Facts - Winning the Battle of the Weeds are probably your best option.
