Fish in Crisis / Ammonia

Pond keeping can be a fabulous and fun experience, but it is important to maintain a clean, healthy environment for your fish. One problem to watch out for is too much Ammonia.  Ammonia is caused by decomposing leaves, excess fish food and is a by-product of fish waste.  Over-feeding and over-crowding also contribute to poor water conditions. One inch of fish for every 10 gallons of water is the rule.  (see overstocked for more information.) 

Improper removal of Ammonia can cause stress & respiratory problems and create an environment that allows parasites & bacteria to thrive.  Flashing or rubbing against rocks or plant pots are signs of irritation of the skin and can be caused by Ammonia or parasites. Even low toxicity levels can threaten fish health. Irritation of the gills can be a sign that Ammonia is beginning to build up. 

In nature, the circulation of fresh water in lakes, rivers and seas continually dilute the ammonia, but in the confined space of our ponds, steps are needed to maintain the proper levels.

An Ammonia test kit is inexpensive and essential.  If you should encounter an ammonia problem, water changes with dechlorinator is the quickest ways to save a fish collection. {{A biological filtration system that can constantly remove ammonia by way of the Nitrogen cycle. }} {{need more information, or a link??}}

For a quick, temporary fix, there are many ammonia blockers and prep kits you can buy, however, the situation must be dealt with on a more permanent level in order to prevent the death of your Koi.
