Fish Tank Facts

Is something fishy going on in your Fish Tank?

Poor fish tank water chemistry can effect fish in many ways, and it can sometimes seem difficult to get it just right or find out what the problem with the fish water is. Things such as high ammonia, nitrate, pH, and temperature can all affect the well being of fish.


Ideal value of ammonia = 0. Ammonia is naturally produced from fish waste from the gills. The toxicity of ammonia relates to ph and temperature of the water which is why it is important to monitor all three. Ammonia is not good for fish as causes lots of problems some even as serious as eroded body structures!


Ideal nitrate value = 0. Nitrates are produced by the break down of waste matter in the fish tank water, this can leave the fish starved of oxygen which could prove to be fatal.


The ideal pH = 7-8. Adverse pH can affect aquatic life in many different ways.

High acidity can erode the gills causing breathing difficulties.

High alkalinity causes Alkalosis which leads to marked gills and skin erosion. Not very pleasant as all.

Temperature: Seek professional advice for the ideal temperature of the water for your aquarium.

Warm water fish cannot survive in water that is too cold because their metabolism slows down and eventually stops. On the other hand over heating of cold water fish makes their metabolism race. Sometimes this can cause respiratory difficulties cannot breathe because warm water contains less oxygen than cold water.

These are just a few of the reasons as to why it is important to monitor water conditions in your fish tank. A quick and easy way to do this is to use the Fish Gem. The innovative in-tank sensors continually monitor pH, ammonia, nitrates and nitrites and temperature and display all the information on a handy touch screen display. What could be simpler?
