How to Shock a Pond Quick How-To Guide
If fish are dying in your pond or if you see lots of algae, it may be time to shock the pond to clean it up. Algae needs oxygen to grow, just as fish and aquatic vegetation do. However, too much algae can rob fish and plants of the oxygen they need. Shocking your pond and getting rid of the harmful algae can restore the clean, clear look to you pond. Because desirable plants and animals live in ponds, owners look for natural enzymes and organic compounds to clear the water. Chlorine should only be used as a last resort.
Remove all dead or decaying plant and animal life from the pond. Algae feeds on the decay process.
Place the correct amount of algaecide in your pond according to manufacturer’s directions. For example, if you have a 120-gallon pond, you would need to use 2 teaspoons of general Algaecide. Each algaecide is different, so read the directions closely.
Let the pond pump aerate and spread the algaecide. If algae is still present after a week, shock the pond again.
Fish Friends for Koi
Fish Friends for Koi
When they are in the wild, Koi live with other species of carp. Koi also get along well with killifish and minnows.
Other types of fish that can be found in the lakes and streams they inhabit are large game fish, such as perch, bass and Catfish.
Koi are peaceful and do not bother or prey on other fish in your pond which makes it great for stocking your pond with a variety of other fish.
Sunfish get along well next to carp with Redear sunfish being the most popular for a carp pond.
Grass carp act as natural pruning system for your pond and they will make great friends for your Koi. Grass carp will also help maintain your plant vegetation as they like to eat and out of control plants that are growing too big.
Since they are similar, goldfish make a great friend for your Koi. They share similar color patterns to Koi and will help compliment the beauty of your precious Koi in their new garden pond.
For other fish, largemouth bass, catfish and striped bass will make perfect mates for your Koi. Bigger fish will require a larger pond size so keep this in mind when selecting the size of your garden pond.
Frogs can be really good friends for your Koi or any kind of amphibian. Local frogs, newts and even salamanders can share the same space as your Koi with no issues.
Try to attract frogs naturally to your pond rather than stocking them from a store. Frogs from pet shops may have bacterial infections or diseases that can spread to your fish. We want to keep your fish as healthy as possible so they can live a long life in your garden pond.
Fish that you want to avoid stocking your garden pond with if you have Koi are Bluegill. Carp and Bluegill are rivals and will be destructive to your garden pond as they compete for resources and food.
Small fish such as nano fish should be avoided too. These smaller fish will not be happy swimming around with large Koi and will be anxious and nervous when in an enclosed garden pond with them.
Lastly, the best option to stock your Koi pond with is more Koi. They like to be in a group or a school and the minimum for that is at least 5. If you have a larger pond, you may be able to accommodate up to 15 individual Koi. Be sure to consult with our professionals about the needs for your Koi pond setup.

Koi Pond Setup
Pond Setup for Koi
Koi are the more sophisticated version of their wild versions which are common carp. Carp are traditionally native to Europe and Asia.
The habitat of carp are lakes, streams and ponds with mud near the bottom and minimal water flow. They can be found in temperate and tropical areas and they like water temperatures over 70 degrees F.
Carp are most active in the dim lit hours near dusk and dawn but they will forage for food at all times of day.
Achieving these living conditions for your new Koi is not a hard task.
Koi Pond Setup
Koi prefer temperatures between 74 to 86 degress F year-round. For areas where it is colder, a heater system will keep them from freezing and protect your valuable fish.
A small stream or waterfall is fine for your Koi but they do not require an water flow to be happy.
For the pH of your pond water, it should be kept between 6 and 9. Crushed limestone can be used to help maintain the pH levels in your garden pond.
For best results, a Koi pond with concrete and rubber lining are best. For the bottom of the pond, a substrate that mimics a mud consistency will have your Koi feeling right at home.
A beautiful outdoor water garden will give the best result for a pond setup. The plants should be non-invasive so they don’t damage the natural ecosystem for your new Koi friends.
The best plants for your water garden will included:
* pickerels
* floating pondweed
* water lilies
* cattails
* water hyacinth
* duckweed and more
Willows and other shade trailing trees around your water garden pond are recommended by other garden pond owners. These will help to provide extra shade and cover for your fish.
How big should your Koi pond be?
250 gallons of water is the minimum for keeping a Koi in a pond. A school of Koi may require over 1000 gallons of water.
Ten gallons of water is needed for every inch of fully grown Koi as a rule of thumb. This same rule can be applied to other fish as well. Because Koi can reach 3 feet in length, this means that 250 gallons is the absolute minimum for one adult.
