There is too much nitrate in the rain, putting too much nitrate into the water. Too much nitrate kills the fish.
Differnt types of fish tanks will need different levels on nitrate. However, most fish tanks benefit from as little nitrate as possible. Saltwater tanks should have almost no nitrates. Freshwater planted tanks conversely, should have about 10-20 ppm nitrate. For most normal, tropical freshwater aquariums, keeping nitrates below 20ppm is acceptable.
All rain has somewhere to run off, rain will carry the nitrate into water streams, causing a surplus of plants-- taking air from aquatic ecosystem=killing fish.
nitrate helps increase plant growth. Nitrate helps build protein in the plant which makes plants grow. Nitrate is found in fertilisers, which farmers place on their crops to make them grow. So yes, nitrate affects plant growth but in a good way!
the affect of the fish thing is like you can't even put a magnet on a fish so yea
Pelicans eats fish, which may affect other animals that eat fish. Also it may affect plant/animals that the fish eats.
For a freshwater tank, its safe to add fish after the the ammonia, nitrite, and nitrate levels are safe for fish. Ammonia and nitrite should be at 0 ppm and nitrate levels should be very low, under 50 ppm. You should also make sure that other parameters are safe for the species of fish that will be living in the tank.
how do any living thing affect puffer fish
Eutrophication, algae, dead fish, the water has a bad odor to it.
yes it can affect the fish because if you holed the fish upside down you can cause it not to breathe because all of the water is out of its system
Nitrate is a nitrogenous fertilizer which promotes growth of algae and greenery. Too much is not good. Depletes the oxygen in the water for one thing
