What are the signs of good water quality?
I want to add fish to my freshwater aquarium, and I want to make sure they have the least chance of dying.

- Check your water parameters, it should have 0 ammonia, 0 nitrite. Some nitrate presence is not lethal as long as it's within the limit.
- Match the pH and temperature depending on the species you plan to put it.
- Water should not be cloudy.
- There should not be any bio-film forming on top of the aquarium. In case it forms, increase surface agitation.
- Make sure your tank has enough filtration to support the bio-load.
- Tank decoration should match the requirement of the species. Some prefer less open area and more hiding place, some prefer the opposite. Some prefer plants, some prefer rock, some prefer a piece of wood.
Some signs of good water quality:
The normal pH levels of 6.5-7.5;
The normal temperature of around 25 degrees Celsius;
no ammonia, nitrite or nitrates present;
algae present in small, controlled quantities.

2I think the first two points are totally species dependent. Some species prefer higher pH, some lower. Some prefers low temperature, some higher. Nov 21 '13 at 9:50

3Most african cichlids prefers pH >8... fishes from amazon basin prefers pH <6. But thats not the point, 6-8 is a big range, having a pH anywhere in between does not mean your fishes are happy. Nov 27 '13 at 6:54
