Keep garden pond and aquarium ammonia under control and understand the nitrate cycle for tank health.
Ammonia is sometimes referred to as one of the “invisible assassins” in aquaria (along with nitrite). The only acceptable ammonia level in an aquarium is zero. . . . → Read More: Ammonia in a fish pond and aquarium
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
Our ponds are home to far more living organisms than the fish we have stocked and see swimming around ever day. A pond is quite literally alive with micro organisms that have colonised to exploit the food and favourable conditions for their . . . → Read More: Biological Pond Filtration
I installed a new 2000 gallon pond in March of this year, constructed using a liner and incorporating an external multi-chambered filter. I have been adding koi to it since Easter and have noticed that the pond’s clarity has deteriorated from its initial crystal clear state . . . → Read More: Cloudy pond water – I can’t see my fish!
A stunning way of bringing living, moving splashes of colour into a garden is by keeping fish in a garden pond.
The fish that are routinely kept in ponds are brightly coloured, ornamental varieties of their poorly coloured natural ancestors. However, one of the most common problems . . . → Read More: Crystal clear 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
It is the role of the aquarium filter to maintain a stable and safe water quality within an aquarium.
If the water quality is ideal then the fish will thrive and be less likely to develop health problems.
An aquarium filter is effective removing solids and breaking down . . . → Read More: Do I need an aquarium filter?
Water quality is the keystone to successful koi keeping. Remove it and koi health problems are likely to follow. There are many different water quality parameters that require constant monitoring with the results and interpretation of water tests essential to maintain a healthy pond.
Q: I understand that good water quality is perhaps the most important way of ensuring healthy Koi, and as such, parameters like ammonia, nitrate and pH should be kept within their recommended levels. But what about other measures of water quality, such as how foamy your . . . → Read More: Foamy pond surface. Why?
Most fish keeper’s are well aware that the pond or aquarium water should be routinely tested for the presence of pollutants such as ammonia and nitrite but very often the oxygen content is overlooked. Oxygen is an essential . . . → Read More: Garden pond dissolved oxygen
It is a long time since I last watched The Wizard of Oz (I didn’t catch it this Christmas) and I can’t recall the finer details of the ending. But what I do remember is towards its conclusion, experiencing a real anti-climax when we were shown . . . → Read More: Garden pond filtration
Every environment shares problems if the inputs into the system are out of balance with the rate at which they are removed or broken down. Currently, on a global basis, this is the case with CO2 and the earth’s atmosphere and it is also true for . . . → Read More: Koi food affects pond water quality
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
The most appealing part of koi keeping is marvelling at a pond full of ornamental beauty. The challenge in achieving that ultimate goal is to be able to understand and master the many practical demands put on a koi keeper. Some of these practical challenges, on . . . → Read More: Koi pond filtration
Installing a bio filter is the price we have to pay for wanting to keep koi in an artificial pond. It performs the functions that occur naturally in a lake or river within a compact unit and is arguably the single most important factor that makes . . . → Read More: Koi pond filtration
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
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
Whenever koi pond filtration is discussed, attention tends to be focused on the biological aspects, with the emphasis being placed on maturation rates, testing for ammonia and nitrite and avoiding new pond syndrome at all costs. But effective pond filtration results from the combination of a . . . → Read More: Mechanical pond filtration
I became a koi keeper by accident two years ago when I bought a house, complete with koi pond.
It is approximately 15 ft long by 8 ft wide and by my reckoning holds about 2500 gallons. It seems quite easy to maintain, especially as it tops . . . → Read More: My pond’s pH is too low and unstable.
Could you please tell me what ‘new pond syndrome’ is all about? I have heard this term before but never really understood it, and I think it’s about time I did, since I am moving my koi to a new pond very soon. Does this . . . → Read More: New Pond Syndrome can cause problems in a new garden pond
Oxygen is the essence of life and is required in abundance in a well stocked koi pond. Oxygen quite readily dissolves passively diffusing from the atmosphere, but this limited amount is insufficient to satisfy the demands of koi and other oxygen-loving pond organisms such as beneficial . . . → Read More: Pond aeration

Q: At various times this summer I have seen my Koi gasping at the pond surface and around my waterfall. Does this mean that there is not enough oxygen in the pond? Is this because of exceptionally high temperatures or for some other reason? . . . → Read More: Pond fish koi are gasping?
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
I am relatively new to koi keeping, having installed a new koi pond in March this year. Taking the advice I have read in your magazine, I have been very careful to find a koi dealer who I believe I can trust.
As koi keepers we are experts in keeping fish in an enclosed artificial environment that is stocked with an unnaturally high stocking level and fed a relatively large quantity of food. Consequently, there will come a time when the pond’s ecosystem becomes unbalanced, requiring our input . . . → Read More: Ponds do need a regular partial water change
Pressure filters for garden ponds first appeared on retailers’ shelves just over 10 years ago. Most of us were then more familiar with the aquarium pressurised canister filters.

Anybody contemplating whether to take the plunge or merely dip their toe into the world of koi would be well advised to carry out as much research on the many aspects of the hobby as possible before getting wet.
Q. What principal water parameters should I check on a day-to-day basis? And what are the recommended levels for a koi pond? Are there any other parameters I should check too? Why is it so important to keep on top of this?
