Get The Best Aquarium Timer – Make Life Easier

Aquarium timers are probably the last item you want to buy for your aquarium hobby. However, a timer can give you a lot of comforts and benefit your aquarium. 

Aquarium timers have been developed to help manage your aquarium equipment and make life a lot easier for you and your fish. However, aquariums are more than just decorations; they’re living habitats that require careful attention and care.

One of the most important things you can do for your aquarium is automate it so that you don’t forget when to turn off the aquarium light or start CO2 injection. With an automatic timer, you’ll never forget it again! A timer controls the lighting and other equipment like CO2 regulator, skimmer, etc. 

A few other benefits of using an aquarium timer include energy conservation by turning off lights and other gadgets when unnecessary and harmful for the fish and aquarium environment. Keeping all that in mind, I have made a list of the best aquarium timers so that you can enjoy the automated aquarium. 

What Is An Aquarium Timer?

These timers are usually simple devices that you set up, and then they turn on or off at preset times automatically without any human intervention required. It is a simple unit directly plugged into a wall outlet or into the light cable having a digital interface to control or mechanical adjustments. 

Some aquarium lights can be controlled remotely with the app; those have Bluetooth capabilities, but often the best way is to plug them into a timer.  

You must find one that suits your needs before purchasing anything too pricey because many of those have complicated interfaces for manual adjustments.

Types Of Aquarium Timer:

Standard Plug-In Timer

These types are probably the best aquarium timer on the market, straightforward to set up and use! First, plug it into your outlet or power strip, then plug in all of your electrical equipment. Then, simply program this little device so that you can control when everything needs to be turned off/on, turning a chore into an enjoyable experience instead. 

Plug-in timers generally have on/off features, are very affordable and widespread. Plug-in timers are great when you have one product that needs to be switched on and off at different times. If, however, your aquarium needs two pieces of equipment with a set schedule, this is not the right option as they only work individually!

The best part is plug-in timers are very cheap, so there’s no problem getting more than one if needed. With this type of timer, you can only turn on/off the light or other equipment. Still, you won’t get the ramp-up feature for lights, like 24 hours day/night cycle, sunrise, sunsets, etc. If you want all of those, you definitely need a ramp-up timer. 

Ramp Up Timer

Ramp-up timers are modern, and they are pretty cool. Wouldn’t you prefer to have your lights turn on and off and gently simulate a sunrise/sunset for your fish? With this ramp timer, it can also do the latter. This dimmer is perfect if you want to give a more natural light cycle to all of those plants and aquatic critters!

Rather than having your timer switch between day and night at intervals, wouldn’t it be cool if it could gradually change from an aggressive daytime cycle into one tailored specifically towards evening activity to better suit them? That’s what gives these “ramp timers” their name-it creates a gradual shift over time instead of suddenly turning everything up or down.

You can program a ramp timer to gradually change your aquarium’s lighting intensity throughout the day, imitating natural sunrise and sunset times. This helps create an atmosphere more conducive for both fish and plant life in order to stimulate their growth better.

Why Does Your Aquarium Need A Timer?

If you are a fish-lover, then take note! Limiting the time your aquarium lights stay on is crucial to keeping algae at bay and maintaining healthy sleep schedules for your pets. 

Turning off our underwater friends’ light after they have gone to bed prevents them from getting stressed out because it hampers the circadian sleep cycle. In addition, you may experience nuisance algae outbreaks because of too much exposure to lights.

However, you don’t need to buy a timer for aquarium lights if you already bought one with a built-in timer. Nowadays, it’s very common for you to purchase an aquarium light. Then, you’ll get the timer to turn it on/off and allow you to play around with different lighting patterns and intensities. 

But, what if you don’t have such a high-tech light, and you have to switch it on/off every day. Moreover, if you have other equipment like a water pump, protein skimmer, UV sterilizers, dosing pumps, and co2 regulators to automate, in that case, you should buy the one that you find best. 

My Choice List Of Best Aquarium Timer

The Coralife Digital Power Center (05152) is a timer and power strip for controlling aquarium equipment such as lights, pumps, filters, and chillers. It features a convenient LCD display to make programming easy and a seven-time cycle setting for creating various day/night scenarios.

Suppose you want to go on a vacation or are too busy to take care of the aquarium equipment operation. In that case, I suggest buying this Fosmon 24-hour programmable digital timer. Then, simply plug the device into the timer and set the timer to control the equipment for you following the 24 hours cycle.

The digital timer features a sleek, white design that doesn’t take up any floor space. The large numbers are easy to read, and programming the schedule is quick and straightforward – even for beginners! In case of a power outage, there’s an internal battery that will hold your settings for over 100 hours without external power.

You can safely use any light fixture as long as it is in the range of 125V/15A and is compatible with incandescent, CFL, and LED lights. The timer doesn’t offer much flexibility, only one ON and OFF setting, making it easy to use. However, other timers having multiple functionalities often make the thing complicated.

Some mechanical timers may cause irritating sounds while it’s turning on and off any device, but this Fosmon timer is super quiet. Unfortunately, you can’t program multiple devices with a single timer; you need a separate timer.


  • Easy to use and program
  • Safe for any device (range is 125V/15A)
  • Elegant, sleek design
  • Doesn’t take much space
  • Quiet operation


  • Only on and off function
