Indicators of bad water quality

I will be using this post to capture things that indicate that the water quality is degrading. I hope to keep updating this post as and when I learn and find out new indicators.

In the past few days I have seen lot of tiny suspended particles in the water column. It is similar to the how dust particles light up when a ray of sunlight shines through a dark room. I knew something was not right. Today the stripes of the neon tetra looked really pale. The ble and red stripes had totally lost the glow. I did some searching online and found that pale colour is usually indication of poor water quality.

I did a partial water change (pwc) but that did not help. I then looked at my filter and though I had cleaned it recently, it did not look good. I cleaned it in the water from the pwc straight away.

Within two hours I could see water clearing and the neon tetras had their shine back. I will have to keep my eyes open for any much indicators that the fish give to keep the tank in good condition.

I have been trying to figure out the root cause and I think that in my case the plant matter is contributing to the bad water quality. The plants in the aquarium are yet to settle in and I see a lot of leaves shed by the plants. Even after siphoning the leaves there are still many lying around. In my opinion the decaying leaves and plant matter is creating the haziness.

Update (26/10/12) - After feeding the fish live worms for two days in a row, I also see that the water is not as cloudy as when I feed them flakes and granules. Maybe another factor to consider for bad water quality is the quantity of the food and type of food.
