Most Common Koi Fish Pond Problems and Their Solutions 0 1532

Koi ponds lend unique aesthetic beauty to lawns and gardens. As you work to maintain an ideal environment for your fish while keeping them healthy, you will surely encounter a number of important issues that needs to be addressed. Being aware of these potential problems can help ensure that you are able to implement measures to prevent and/or address such issues before it?s too late.

High pH

The recommended pH of Koi ponds range from 6.8-8.2, with 7.0-7.5 as the ideal values. As pH level in the pond increases, it can give rise to a life-threatening situation that will endanger the life of your fish. Although there may be natural fluctuations in the pond?s pH, this is not something to be concerned about as long as they remain insignificant. However, extreme pH fluctuations and pH levels that are outside the recommended range can increase your koi?s vulnerability to bacterial infection.

Predators are usually active during the night. Being outside, the inhabitants of the koi pond are vulnerable to predators including cats, raccoons, and other wild animals known to prey on fish in ponds. If predators are an issue for you and your fish, it is advisable to consider making the pond deep enough or by placing a net on the water?s surface that will act as a barrier between the predator and the pond?s inhabitants.


Parasite species that can infest on your fish are often microscopic and are difficult to identify. To prevent parasitic infestation, it is wise to invest in an excellent filtration system that incorporates a UV sterilizer.

Poor oxygen levels

As oxygen levels in the pond water decreases, this creates a dangerous situation that can be fatal for your koi. Unfortunately, many pond owners fail to realize they are besieged by this problem until it is too late. You can help ensure that adequate oxygen is present in the pond water by adding aquatic plants or a small garden fountain or waterfall.

Excessive algal growth

Algal bloom can interfere in the koi?s ability to see. Excessive algal growth can also result in less available oxygen for your fish. To address the problem, you can reduce the algae?s exposure to sunlight by tinting the pond water or by adding a small amount of salt to the pond water. However, before adding salt, make sure you don?t have any plants in the pond which are not salt tolerant.

Keeping exotic fish as pets 0 1831

Exotic fish

There’s something mesmerising about watching a tank full of brightly coloured fish swim around. Do they make good pets though? Is it hard to keep exotic fish? With the right pet care and pet advice, exotic fish make great, if unusual pets.

Tank size

Go for the biggest sized tank you can afford and have room for. The bigger your tank, the easier you’ll find keeping the balance of the water right. Your fish need plenty of room to swim too. Aim for at least a 20-gallon tank.

Tank set-up

You’re going to need a heater to warm the water. You’ll also need a filter to ensure clean, healthy water, which is crucial for fish to thrive. It’s advisable to add an air pump to boost the oxygen levels.

You’ll also need a light for the tank, and a timer for the light, so it’s not on all the time. Bear in mind a fish tank should be placed out of direct sunlight, away from draughts and heating sources.

On top of the things that make your tank work you’re going to need everything that goes into your tank; gravel for the bottom, plants, and decorative caves and tunnels so your fish can hide if they want to.

You can usually buy aquarium starter kits at pet food stores if you want help in pulling everything together.

Getting the water right

The filter will cycle your water to make it suitable for fish to live in, never add tap water directly to the tank. You need to de-chlorinate it first. You can also add a water treatment to help keep the water healthy between changes.

You should change about 10-15% of the water each week to keep it clean and healthy for the fish. Never do a full tank change once your fish are in the tank.

Choosing your fish

When you choose your fish, make sure you start introducing them slowly – this will help you identify if you’ve got the water balance right, and at this point, your tanks eco-system is still developing, so adding lots of fish can damage it.

There’s a wide range of tropical fish to choose from – Cichlids, Betta and Swordtails are good starter fish, and are nice to look at. Never mix goldfish and tropical fish together.
