How Much are Koi Pond Prices in Colorado Springs?

Koi Pond Prices

Koi Pond Prices

One question we get frequently is, "What are the average koi pond prices in Colorado Springs?" The short answer is, "It depends." Just like when shopping for many other items, there are base costs and then upgrades, which can in many cases increase the price quite a bit.

When shopping for a pond contractor service in the Colorado Springs area we suggest you do your homework and make sure you are hiring a true pond contractor. many landscape companies claim to build koi ponds and other types of water features, but often are not qualified. Think of a koi pond contractor like a specialist. Would you want your General Practitioner doing your knee surgery? Probably not!

Koi Pond Prices

A basic sized fish pond would be about 7' x 10' and about 18 inches deep (max depth).  If it’s constructed with the necessary components (mechanical & biological filters), rocks, aquatic plants and fish the cost is probably in the range of $7-$10,000. You can easily increase that price to $12-$15,000 if you want to add things like:

  • Fish Caves
  • Algae Control System
  • A longer Stream
  • or Lights

Colorado Pond Pros has built several hundred ponds over the past 16 years in the Colorado Springs, Longmont and Denver areas.

Does My Pond Need a Cleanout?

Does my pond need a cleanout?

Balanced ponds may need to be cleaned out every couple of years.  Ponds that struggle with balance may need annual cleanouts. Take a look at your pond.

◊  Is the water brown, black or unclear?

◊  Do you see muck or sludge on the bottom of the pond?

◊  Is your pump struggling to work because of excess debris around it?

Ponds are ecosystems.  When they are in balance, the water should be clear.  There may be a touch of algae here or there, but not excessively.  When the water looks good, the plants and fish are thriving you still might need to have the gunk cleaned out.  Ponds in Colorado need to run all yearlong to help clean the water clean.  Leaving the water stagnate over the winter can breed slimy composted sludge that has to be cleaned out in the Spring.  Learn more about ponds in our Ponds 101.  Wondering if your pond needs a good cleanout?  Contact us and text us over some pictures -  we'll help you figure out if a cleanout is right for  your pond.

What exactly is a pond cleanout?

When we perform a pond cleanout we:

  • Remove the water from the pond
  • Safely transfer the fish into a portable pond that we bring.
  • Pressure wash every surface of the water feature including streams and waterfalls.
  • Clean out equipment like skimmers, biofalls and canister filters.
  • Check all equipment for proper operation.
  • Check for any lights that may need to be repalced.
  • Remove the gunk from the pond.
  • Cut back plant material as needed.
  • Fertilize lilies.
  • Put clean water into the pond.
  • Add water treatments to establish a healthy ecosystem balance and to protect the health of the fish.
  • Replace any rocks that may have been disturbed during the cleanout.
  • Return fish to the pond.
  • Consult you about the on going maintenance of the pond so that it will be beautiful all year long!

What about barley straw?

clear pond Barley straw helps keep algae at bay.

When using this type of algae treatment, it is imperative that it is organic.  Straw that may have been treated with pesticides could kill the plant life and even the fish in the pond.  It usually comes in a small "bale" that can be placed in the pond and weighted down by tying a string to a rock that is attached the the barley straw bale. As it begins to decompose, it creates and enzyme that helps to reduce algae.

How long does it take to work?

You won't get instant gratification here!  This may take 4 to 6 weeks to really get going, so we recommend adding it in early spring.  Adding it at the time of a cleanout is even better. While a bit of patience is needed, it pays off. Barley straw can keep a pond looking great all season long, because it lasts about 9 months!

Make sure you are adding the correct amount of barley straw for the size (gallons) of your pond.  Directions generally come on barley straw that can be purchased over the internet.

Raccoons can become a pest if they realize you have fish!  They are brave and clever, deterring them can be difficult.  Try these things to get ride of a raccoon at your pond:

♦  Put in a fish cave for your fish to hide in

♦  Provide plants like lilies and floating lettuce to help hide the fish

♦  Leave your dog in the backyard - raccoons don't want to deal with dogs

♦  Use mountain lion urine.  Yep.  Mountain lion urine can be obtained from many garden centers or on line.  Follow the instructions on the container.  It should deter those pesky raccoons!


How Many Gallons of Water in a Pond?

How are  gallons of water in a pond calculated?  We use the calculation of length x width x 80% x average depth x 7.48.  Why 80%?  Ponds are usually not square, but about 80% of a square. You may have a round pond that is shaped more like a kidney bean, an off centered oval or a natural flexible shape like the pond pictured here.

What is with the 7.48%? There are 7.48 gallons of water in a cubic square foot.

(L x W x 80%) x average depth x 7.48 = gallons in a pond.

So  a 10 x 8 pond with an average depth of 2 ½ feet it would look like this:

10 x 8 x .80 = 64.  64 x 2.5 x 7.48= 1,196.8 gallons.

Why it is important to know the gallons of water in your backyard pond?

When you purchase beneficial bacteria, algaecide or other products, the directions will specify the amount to put in based on the gallons of water in the pond. While it may not seem like a big deal, over dosing a pond with a product could cause fish and plants to die.  Always know the gallons of water in your pond for safe addition of products to help your pond stay in balance.

Fish Food Storage

Storing Fish Food - It matters!

Proper storage of fish food is essential to keeping it from going bad or getting mice, cats, mold or weevils in it.  As long as you have a fairly small container, a shelf in the garage might be fine.  If you buy it in larger quantities, don’t put the food in the freezer.  That can degrade the nutrients in it.  Put it in the fridge for best preservation.

If the food is old, it may smell funny or have a fuzz on it.  It my change color or consistency.  If these things happen you’ll have to throw it out.  Feeding fish spoiled food can cause them illness!  Better for them to wait a few days to be fed while you get some fresh food than to eat something that may hurt them.  In the meantime you could give them a bit of green lettuce or some fruit.

Do I Need Plants in My Pond?


Cordata Chameleon

Plants bring a new level of beauty to any pond, but they are much more than just good looks!  Plants in a pond are the natural workers of a healthy ecosystem. They use nutrients that fish are adding to the water (fish poop!) and therefore become living filters!  Too many nutrients in the water can cause algae blooms and sludge.  Too much sun on the water can contribute to algae growth as well. While plants are sitting there looking beautiful, they’re actively providing filtration. When plants cover 30 to 40% of the surface area of the pond, it will reduce the temperature of the pond, helping reduce algae blooms.

What about fish and plants?

In addition to filtration, your plants are good for the fish.   They create a shady place for fish to relax.  Some fish will nibble on the roots of floating plants like water hyacinth or water lettuce. Both of these will spread and can be quite lovely.  Here in Colorado these are annual plants, so they will die off when the winter weather comes.  If your fish have babies, plants offer a great place for them to hide.  

To have a balanced ecosystem a pond needs the following 5 components and plants are #5!

  1. Filtration (skimmer)
  2. Rocks and gravel (surface area for good bacteria to colonize)
  3. Recirculation (oxygenation - pump, aerators and good water flow)
  4. Fish (keeps algae in check)
  5. PLANTS (cleans pond by adding living filtration)

Do I Need to Do Anything Special For My Fish to Have Babies?

You don't have to do anything special for your koi and gold fish to have babies.  Fish will spawn and have babies all on their own as long as you have a healthy pond.   Goldfish and koi are egg layers. Gold fish spawn readily while koi take a bit longer. Usually in the late spring or early summer they produce thousands of eggs.  Most don’t survive to grow up to be baby fish.  

Did you know baby fish are called “Fry”?

The fry will hide in the gravel on the bottom of the pond for a few days and then they will go hide out in the plants.  If you don’t have plants, chances are the fry will become tasty snacks for the adult fish in the pond. If the gravel is too clean, less fry will make it. They grow about an inch per month for the first year.

Can Koi and Goldfish be Kept in the Same Pond?


Koi and goldfish can be kept in the same pond, but there are a few things to keep in mind.   

Both koi and goldfish can be beautiful and they come in a variety of colors.  Koi will breed with the goldfish.  Some of the baby fish (fry) will be born brown or grey and may turn orange as they get older.  These fish will not be pure koi, something that doesn't really matter unless you are really into koi! 

What about having too many fish?

Fish will procreate like crazy in a healthy pond.  Goldfish will eat koi eggs and fry (baby fish). While very few will make it, the population of the fish overall will stay at a manageable rate.  Wondering how many fish your pond can sustain? Read How Many Fish Can I have?, in our Ponds 101.
