Koi Pond Water Testing Parameter

Koi pond water quality is a determinant of koi fish health, So we have to constantly monitor water quality continuously. We can monitor the koi pond water quality with water testing steps. Water testing is perhaps the most important part of Koi keeping as this can tell you a lot about whether or not your pond filter is working at peak efficiency.



Parameters that need to be tested for water quality are:
1. Testing and monitor ammonia, and the presence or not of this will confirm for you whether or not your filter is performing satisfactorily, or whether it's efficiency is falling due to causes that need urgent investigation. Using Ammonia tester kit can monitor value current ammonia disolved.

2.Then monitor nitrite (don't confuse this with nitrate), as nitrite appears after the first stage in the oxidation of ammonia. You can have the situation where there is no ammonia, yet nitrite persists, and this should lead you once again to investigate the filter performance.

3. The third parameter of importance is pH. This can tell you a lot of things about your pond, and there is a certain band, which is better, suited to Koi. PH 7.5 to pH 8.3 is absolutely ideal, but Koi can exist from pH 7.0 to pH 8.5 without harm as long as it is stable.

Any reading outside this range should be investigated and rectified without delay, but we would not advise that you tried any alteration of pH by artificial means such as the widely sold "pH buffers". Not only would this require a lot of buffering agent, but it would not be a permanent correction, would need to be repeated often, and you could thereby be masking a filtration defect.

This Koi keeping hobby is, as you can see, rather a complex one but with a little learning applied and a little common sense, we can hopefully surmount all of the difficulties that others fall into, who are not prepared to acquire this knowledge and to apply it.
