How to test and what to look for. If things aren’t as they should be, how do you improve things?

Ammonia in a koi pond

Ammonia is a wonderful thing when you’re washing your windows. It’s not so wonderful when you’ve got a pond, especially one with fish. Ammonia can be very harmful, even deadly, to koi and goldfish, smells bad and can promote soupy green algae. Luckily, it’s easy to . . . → Read More: Ammonia in a koi pond

Discoloured tinted pond water

A koi pond’s stability is often overlooked as one of the most influential factors in maintaining koi health. We can often be guilty of forever tweaking and adjusting water quality in our quest for ‘perfect’ water quality. With respect to water parameters such as pH and . . . → Read More: Discoloured tinted pond water

Dissolved oxygen and pond fish

Dissolved Oxygen Concentration (DOC) is the term given to describe the amount of oxygen that is dissolved in pond water.

Dissolved oxygen is measured in terms of how much oxygen (by weight – mg) is dissolved in every litre of water. There are many factors that will . . . → Read More: Dissolved oxygen and pond fish

How to test garden pond water

Time and time again we read and are told that water quality is of paramount importance when keeping fish, especially koi.

It should lie at the centre of every serious koi keeper’s plans, from the moment we start to consider the plan and design of our koi . . . → Read More: How to test garden pond water

Koi Pond Chemistry

As koi keepers we are more water keepers than biologists, and as water consist of H2O (as well as everything else dissolved within it) we owe it to our koi to understand a little chemistry. This will then increase our success and fulfilment, ultimately benefiting our . . . → Read More: Koi Pond Chemistry

Koi pond oxygen

Koi breathe by pumping water over their gills to extract essential oxygen, which is invisibly dissolved in the pond water.

Fortunately, compared to other fish species, koi do not require an especially high level of dissolved oxygen (DO) which makes them relatively undemanding in this area. Even . . . → Read More: Koi pond oxygen

Managing pond water quality – Regular testing

Keeping fish is not like keeping any other pet, such as a cat, dog, rabbit or guinea pig as they are unable to escape from their pond. If four-legged pets take a disliking to their surroundings or become stressed in their environment in which their owner . . . → Read More: Managing pond water quality – Regular testing

Pond pH keeps changing

Koi benefit significantly from stable water conditions, where water quality parameters such as temperature, dissolved oxygen, ammonia and nitrite should be maintained within desirable levels. This is especially true for pH which must be remain consistently between pH7 and pH9

pH is one of the most widely . . . → Read More: Pond pH keeps changing

Testing Pond Water Quality

As pond keepers, we spend a great deal of our pond budget on buying a pump and filter so that we can provide our fish with a good healthy environment. Water quality has a very direct and predictable influence on the health and well being of . . . → Read More: Testing Pond Water Quality
