What is the best aquarium chiller brand?
A few weeks back, I had a major set-back with my display tank. While working under my tank, I messed up the temperature my heater was set at…unfortunately at the same time I was leaving for vacation, which was also during a heat wave. Long story short (you can read about that story here), my tank heated up significantly and caused some of my corals to die. Once that happened, I set out to figure out how to prevent that from happening again. What I realized is that the best insurance policy against your tank hitting unsafe elevated temperatures is to have an aquarium chiller. Until then, I had never considered a chiller, so I set out to find out what the best aquarium chillers were.
What I found out is that the best aquarium chiller is the one that is the right size for your aquarium, at the right price. The aquarium chiller shouldn’t be too big or too small–it needs to be just right, or it won’t be able to properly cool your tank, when needed. In this article, I will describe how an aquarium chiller works, how do you know if you need an aquarium chiller, why is high temperature bad, how much does it cost, how do you set one up and I will also provide product reviews for some of the best aquarium chiller brands. If you are interested in just jumping ahead to check out the products and prices for yourself, here are a few affiliate links where you can learn more about these products, including their price, on Amazon.com:
How does an aquarium chiller work?
An aquarium chiller is like an air conditioner for your water. There is a thermostat, that monitors the temperature and switches the aquarium chiller on when the water temperature gets too high. When the chiller is on, tank water flows inside the chiller and gets cooled off in a heat exchanger before being returned by the pump to your aquarium.
Do I need an aquarium chiller?
Technically, you may not need an aquarium chiller. I’ve been keeping fish for almost 30 years now and never previously had an aquarium chiller. But very recently, I had an issue where my tank water heated up…and caused big problems. I don’t want risk it any more, so I’m getting an aquarium chiller–to protect against error and protect against loss.
Why is a high water temperature bad?
- Temperature changes, in general, are bad
- Warm water holds less oxygen
- May cause problem algae growth
Top reviews: What are customers saying?
When properly sized (large enough to lower the temperature of the tank sufficiently when just running for a few minutes each hour…not continuously) and installed, an aquarium chiller is a great product that will keep your aquarium temperature from elevating into the danger zone. People who live in hot climates boast about these workhorses doing the job day in and day out without a hiccup. The top brands are quiet and should run without issue.
Most common complaints
The most common complaints about aquarium chillers are:
- Sometimes they break–there are reviews (in the minority) of products that failed after a short period of time
- Manufacturers are not always as responsive as hoped for in resolving any issues
- Can be loud–may sound like ‘an old refrigerator’ when running
Factors that can impact the performance of an aquarium chiller
To keep your aquarium chiller working properly, keep these things in mind:
- Avoid extreme temperatures–if the temperature in the room is in the mid-to-high 90’s, just about any chiller is going to have some trouble keeping up. If this is something you expect to happen in your home–you want to pick a significantly oversized model
- Don’t forget about the heat load contributed by your equipment. If you are running serious metal halide lights close to the water–you’re going to have a lot more heat to dissipate than your neighbor in the same town who is running cool LEDs
- Your chiller needs good ventilation to run properly–be sure to place it in a well-ventilated are.
- Just like an air conditioner, you need to keep the grill clean to avoid over-working the system
- Ensure you are equipping your aquarium chiller with a properly sized pump to enable the appropriate water flow for your particular model. Follow the manufacturer’s instructions to ensure you have the right sized pump.
How much does an aquarium chiller cost?
An aquarium chiller will cost anywhere from about $260 to over $1,200, for the biggest and best models. One of the most commonly available sizes that should be large enough to handle an aquarium in the 125-150 gallon range or smaller is the 1/4 HP model, which benchmarks at about $600 for all but one manufacturer.
If even the least expensive models are out of your price range, you may want to consider an aquarium fan, like the Aquacool, which can help keep your tank water a bit cooler by facilitating evaporation.
