Before you go ahead and purchase an aquarium chiller, let’s take a look at what are the most important features you need to search for in order to find the best fish tank chiller. Check them out below:
Chiller or Fan
When searching for the best aquarium chiller, you will find out that there are two types: chiller or fan. Picking the right type of unit for your aquarium is quite essential, especially since both types have their pros and cons. Fans such as the Petzilla Aquarium Chiller are great for beginners who don’t want to get complicated and install a chilling unit. That’s not all, fans are also more affordable, and you can purchase more fans as your budget grows. On the other hand, chillers are the best choice for bigger aquariums. They do a much better job of lowering the water temperature and have special refrigeration plates that let them work without a pump. However, aquarium chillers are usually not-budget friendly.
One important feature that often gets overlooked is the noise of the chilling unit. This might come as a surprise, but chillers that run continuously will make a loud noise, and this is troublesome if the aquarium is placed in the bedroom or the office. Luckily, there are units such as the IceProbe Thermoelectric Aquarium Chiller that are designed specially to run quietly. We also want to mention that fan chillers make more noise than the ones that use refrigeration agents.
If you paid attention to the products that we reviewed today, you probably noticed that their power is represented in HP. The power ranges from 1/5HP to 1/3HP. Here is where you will need to do some research because finding the best aquarium chiller requires you to select one that is powerful enough to maintain the temperature in your fish tank. We highly recommend the Active Aqua AACH10HP Water Chiller that is great for 10 to 40-gallons aquariums. The versatility of this unit is quite impressive.
Aquarium chillers run on electricity, and therefore, picking one that doesn’t use too much energy is always a good idea. The JBJ Aquarium Arctica Titanium Chiller is an excellent example of a power-efficient fish tank chiller that will save you lots of money in the long run. With that said, we highly advise you to compare models and take into consideration how much energy they use in order to run at peak performance levels.
Frequently Asked Questions
What is the best aquarium chiller?
The rule of thumb when selecting the top 9 products reviewed by us today was that all of them need to be of premium quality. Therefore, you can’t make a wrong choice here as long as you take into consideration the capacity of your aquarium. If we had to pick one as the best, then we would go with the premium Active Aqua AACH10HP Water Chiller.
How do chillers work?
The definition of aquarium chillers is that they are special devices that can reduce the temperature of water in a fish tank and keep it at a safe level for your species. Chillers are available in multiple types, and the most popular ones are fans that blow air across the surface or refrigeration plates that pumps the water. A reliable aquarium chiller is a “must-have” because it allows you to choose a preferred temperature.
Are aquarium chillers difficult to assemble?
If you are not an experienced hobbyist, then you are probably worried that installing an aquarium chiller is going to require a professional or power-tools. Fortunately, this is not the case. Aquarium chillers are easy to assemble, and they also ship with written instructions that show you how to do everything in a step-by-step guide. Not just that, you can also type in the name of your fish tank chiller on YouTube, and you are guaranteed to find at least one instructional video.
Why do aquariums overheat?
Are you wondering if getting a chiller is mandatory and why do aquariums over-heat? A chilling unit is necessary because many factors impact the temperature in a fish tank. For example, the temperature in people’s houses is usually higher because no one likes sitting in the cold. This will slowly but surely impact the aquarium’s water temperature. In addition, equipment such as pumps and lights that are used for aquariums will make the water overheat.
How do I clean an aquarium chiller?
Maintenance work is the most annoying thing about aquariums, and luckily, cleaning a chiller unit is not complicated at all. You can start by disconnecting the water pipe connections to the chiller. Repeat the process for the electrical connection, and from here on, you only need to rinse the chiller with clean water. If you have a saltwater aquarium, then you will probably also need to clean the calcium deposits. The Hamilton Aqua Max Aquarium Chiller is a great choice here because the front grill is easily removable, and it also ships with a reusable filter.
