Just moved into a new home with Koi Carp pond with 22 fish, why would the water start to smell? -Tracey

That smell is probably ammonia buildup in your pond due to inadequate filtration.

A short term solution is to do a big water change and to cut down on feeding your Koi. Make sure to dechlorinate the new water before you add it to the pond.

You will need to get a good filter for your pond, long term exposure to low levels of ammonia in the water will poison your Koi. Here's an article with more on filtration.
