Water in an aquarium needs to have its temperature maintained so that oxygen content in water doesn't go above a critical temperature.Using a water chillier with an aquarium water solution can be highly beneficial for the health of fish because lower temperatures means higher oxygen content. For example, a system in most cases uses a protein skimmer, circulating pump to circulate the water solution, air pumps and many other products that can add heat to the water. Add to that the ambient temperature of the surroundings and water temperatures in an indoor aquatic environment can rise to levels where oxygen content in the water can be extremely poor.
Water is a well known conductor for heat hence why it is used as a coolant in automotive, industrial and manufacturing processes so in some cases it will require cooling to maintain the aquatic health of your aquarium.
Good Oxygen Levels:
aquatic situations require a good mg/L oxygen content and water can hold
more oxygen at lower temperatures, but this depends on your fish's needs.
In most systems the ideal water temperature needs to be between 24DegC and
27DegC. The temperature set point really depends on the system being used.
When the water is cooled to an acceptable temperature the aquarium can
flourish with a good level of oxygen and steady temperature of the water.
A good example regards temperature and oxygen content in water, at 30DegC
fresh water can hold up to 6 mg/L while at 20DegC fresh water can hold up
to 9mg/L, almost 50% more oxygen content. That means a whole lot more
Water Oxygen Content:
Important Options When Buying A Aquatic Water Chiller:
is very important to buy a water chiller with a titanium heat
exchanger. If your chiller has not got a titanium heat exchanger
than contamination between the metal can spoil the water solution. Because
some solutions have an acid or alkaline content this can corrode cheap
base metals to the extent that metal perforation and contamination of the
water becomes a issue to your background water levels.
Sizing Up Your Water Chiller:
If you are using a system with 1 x 150 litre in the tank you will require:
x 150 litre tank = 150 Litres
Litres = 150 Litres
10% for heat losses = 15
Total Required = 165 Litres
you will require a chiller with a rating of +165 litre cooling capacity.
Pro's and Cons of a water chiller:
water chiller combats heat where it matters
oxygen levels in the water
pathogens in the root mass of plants
Ideal for any system
water chillers have an air filter which acts as a air cleaner
heat load from the water chiller has to be extracted from the room
or heat will be added to the ambient air.
or heat will be added to the ambient air.
levels and vibration from cheap water chillers can be annoying
water chillers don't have a titanium heat exchanger
