What is An Aquarium Chiller and Why Would I Need it?
Your aquatic life requires a perfect environment for flourishing in the aquarium.
You would not want your negligence to be detrimental to the fish.
Aquarium chillers are meant to lower the temperature of water in the tank to the desired levels that are suitable for the fish.
Aquariums tend to overheating.
Fish and other aquatic life are cold-blooded. This implies that they do not have autonomous body control.
During summers, when the weather gets too hot, you switch on the AC for your comfort.
On the other hand, aquatic life requires AC for their survival rather than comfort.
Fish cannot withstand high temperature.
Therefore, if you have an aquarium and want to make sure that you provide your precious fish with the best possible care, you need to get your hands on an aquarium chiller.
Why Do Aquariums Get Warm?
Various factors can contribute to the increase in temperature of the water in the tank.
How Does An Aquarium Chiller Work?
The function of aquarium chillers is to reduce the temperature of the water.
It does so by removing the heat from the water and transferring it to somewhere else.
As the heat is removed, this process leads to the cooling down of water, thereby leading to a drop in temperature.
Keep in mind;
Heat moves from a warm source to a colder one, and this is the principal that chillers use.
Four components are present in a chiller, namely
- Heat exchanger or evaporator
- Condenser Coil
- Expansion valve
What Should I Consider while Buying An Aquarium Chiller?
Your fish is at your mercy. It is your responsibility to ensure that they get an ideal environment to thrive.
Therefore, it is vital to make sure that you buy the right chiller for your tank.
Is Water Flow Necessary for Aquarium Chiller?
Yes. Water flow is highly essential for the optimal functioning of the chiller.
It is the water pump that pushes the warm water of the tank through the chiller, passing it over the heat exchanger and getting it back to the tank.
The cooling process is gradual.
Understand this; the water needs to be circulated through the chiller continuously if a stable temperature is to be maintained in the tank.
If the flow of the water is too fast, the chiller will not get the opportunity of cooling it down efficiently.
On the other hand, a slow flow will cause the lines to freeze, thereby damaging the coils and compressor.
Ideally, you can use a separate circulation pump for moving the water through the chiller.
Indeed, some aquarists use filter pump for moving the water through the filter and chiller.
Keep in mind; irrespective of how your chiller is set, the right water flow is essential.
Manufacturers of chillers usually specify the recommended flow rate of the unit.
This will help you in making sure that the right pump is selected.
There is more;
The flow rate specified on pumps usually does not take the pressure needed to push the water through a filter and height into account.
The flow rate of pumps decreases with the increase in the head.
Reliable brands usually offer a chart where you can find the flow rate against the water height or head.
Therefore, you need to make sure that your chiller matches the flow rate that your pump offers and vice versa.
The low flow rate will affect the function of the chiller.
Is it Necessary for A Chiller to Have Thermostat and Temperature Control?
Some units are integrated with controllers and thus can operate automatically.
First of all;
Set your desired temperature, which is the temperature you want to be maintained in your tank.
When the temperature exceeds your set temperature, the chiller automatically lowers it down.
The extent of the temperature lowered depends on the cooling power of the unit, its adjust-ability, and settings.
Those units without a temperature controller have to be turned off and on manually.
If you do not have a thermostat, you have no way of finding out if the chiller is performing its function correctly.
How to Install The Chiller?
This depends on the type of chiller you buy.
Mostly, there are two types of chillers in the market, drop-in and inline.
The heat exchanger coil in drop-in chiller has to be placed in the sump for operating.
On the other hand, inline chillers are different.
They require the water to be pushed through them for the cooling following which the water is circulated back into the tank.
These chillers come with a manual which would guide you regarding the whole process of installation.
Rarely, you might require professional help for the purpose.
Where Should I Place The Aquarium Chiller?
Aquarium chillers work by extracting heat the water, releasing it into the air.
Therefore, placing them in the aquarium cabinet is not a very smart idea.
Think about it;
If you place the chiller in the cabinet, the chiller will dump heat in it, and the aquarium can likely reheat again.
Chillers are provided with a fan for blowing the air across the hot condenser coil so that heat can be removed from the refrigerant.
It is advisable to place aquarium chillers in a place where there is sufficient airflow.
This will make sure that the expelled heat is carried away from the tank.
If you place the chiller in a place where it cannot release heat, it will lose its effectiveness.
To top it off, energy would also be wasted.
Therefore, make sure that if you are keeping the chiller in an enclosed space, it has adequate airflow for carrying the heat away.
It is recommended to leave about 12 to 18 inches of space around the unit.
How Should I Clean The Aquarium Chiller?
First of all; disconnect the connections of water pipe to the chiller. The same has to be done for electrical connections.
If you have a freshwater tank, cleaning the chiller would be a breeze.
Here’s the thing; rinse the chiller with clean water and your work is done.
On the other hand;
If the chiller is used with saltwater, it might contain some calcium deposits.
The deposits have to be removed. You can use vinegar for the purpose.
Can All Chillers be Used with All Types of Aquariums?
No. You cannot use any chiller with your tank without paying heed to specifications.
Can I Use A Thermoelectric Cooler Instead of A Chiller?
Thermoelectric coolers refer to solid state heat pumps.
They use the Peltier effect for their operation.
The Peltier effect comes into play when the DC flows through two conductors that are different.
The heat moves from one side of the ceramic plate to another when current passes through it.
Thus, a temperature difference is created between the plates.
When these coolers are used in aquariums, they operate by absorbing heat from the tank via a probe that sits in the water.
This heat is then transferred to the heat sink present above the water.
The heat is drawn away from the sink via a computer fan.
These coolers have a compact design which works great for aquarium setting.
However, the installation process is complicated.
You will need to drill through the tank or suspend the probe into the water by mounting it above the tank.
The thing is;
These chillers are effective for quite small tanks. Their maximum capacity is 10 gallons.
Furthermore, if the tank has a lot of sources of heat such as reef lighting or pumps, their performance is not satisfactory.
Other Related Questions
What can I do to lower down the temperature in my aquarium?
It can be quite alarming to find that the water temperature has risen significantly in your tank.
However, you can deal with this situation with some simple steps.
- Turn off the lights of the tank
- Ensure that the tank is not exposed to direct sunlight.
- Remove the lid from the tank to let the heat out.
- Place a fan nearby such that it blows directly into the tank across the water.
- Float icepacks in the tank.
Do axolotls require a chiller?
Yes. Axolotls may require a chiller in warm climates.
The water needs to be kept within the optimum temperature range for them,
The suitable range for axolotls is from 60 to 64F.
Remember; they also need to be kept away from direct sunlight.
