Large VS Small Tanks
Though it may seem strange to think that larger tanks are easier to maintain than smaller tanks, it all has to do with the water volume in the tank. Small fish tanks like BiOrb Life 30L, Fluval Edge 23L or Fluval Edge 46L, contain less water than large tanks and small water volumes are more easily affected by outside influences. For example, if the aquarium heater in a five gallon tank were to give out it would not take long for the water in the aquarium to become cold. A larger tank, for example Red Sea MAX 250 Marine Aquarium or Juwel Vision 450 Aquarium, however, holds more water and, thus, would not cool quite so quickly. The water volume in a fish tank also plays a role in maintaining stable water chemistry. As your fish excrete waste and as uneaten fish food builds up on the bottom of your tank, harmful toxins like ammonia and nitrites are produced. While in small tanks the presence of these chemicals can quickly affect water quality, large tanks have a greater water volume to dilute these toxins. This is especially important for new aquarium hobbyists to realize – the greater water volume in larger tanks is more forgiving of the mistakes novice aquarists are likely to make than smaller tanks.
Why not consider bringing a small part of this ecosystem into your home?
