The easiest and fastest way to gauge water quality is to look at your fish,

If they are sat on the bottom , clamped fins or generally 'out of character' this could be a sign of poor water quality.

Unlike most other creatures that can up and move somewhere else they are trapped in their own eco system at mercy to conditions they can not control.

Why?

First thing to do if you suspect water quality problems, is ask yourself why.

Put new fish in?

Used pond treatments?

Feed too much food?

Different water temperature?

Filter not been cleaned recently?

It is no good testing straightaway with a test kit if you do not play dectective to what caused it.

Second thing is test the water using a reliable test kit.
