WATCH: A koi fish aquarium built right into the steps of a HDB unit entryway
Live in an HDB flat with no space big enough for an actual pond to keep Koi fishes? A HDB dweller didn’t let the limited expanse of public housing stop him from building a koi pond at his doorstep. No, literally at his doorstep — the small stairway to a ground-level unit was successful converted...

Copper is ubiquitous in our environment - from pesticides to pipe. Some copper gets into our ponds and this study shows how even small amounts affect Koi in many damaging ways. This study goes into great detail to show the effects on the brain, blood, liver, gills, and kidneys based on very low exposure to copper.
This study evaluates the toxic residual pharmaceuticals in the water as they affect algae, the environment and fish. The results indicate that there are numerous other external factors that complicate the testing. An interesting study, not directly related to our Koi, but certainly affecting our water sources. The list of chemicals they tested for is staggering!
This study examines the effects of nitrite poisoning, and how to prevent it. As a further benefit, the study examines the carp's ability to recover. This is something every Koi keeper needs to know, as it will be useful each time a filter is 'started.'
