Keeping fish requires a lot of steps to take, so why don’t you let this item help you out? Let’s find out what it is and why it can successfully cope with all tasks mentioned above.
What is Auto Top Off System?
The name sounds quite weird, so it is easy to understand that some people get confused when they heard about the system. In fact, an Auto Top Off System is designed to notice the level of water in your tank automatically. Therefore, the amount of lost water will be refilled immediately if it detects any deficiencies.
The combination of an auto top off system and an auto fish feeder is becoming popular as you nearly do not to take care of your fish aquarium so often like before. As a result, you will have more spare time to pursue your hobby, or simply spend time with other family members.
Next, we will do deeper to see a basic structure of an Auto Top Off System as well as the main function of each part. From that, you will have a general idea of how this item works.
What does the box include?
There are zillions of products available in the market with different technologies to help you top off your reef tank. Based on your personal needs and other contributing factors which will be introduced later, you will find the best Auto Top Off System. However, all system will have 3 basic components to function normally:
- Water reservoir
- A pump
Earlier, you might ask yourself where this item takes water out to refill your tanks, and the answer is a clean water reservoir. Yes, all systems are equipped with a reservoir to store water that is ready for the replacement at any time. Plastic jugs and 5-gallon buckets are the most popular types of reservoirs that fish keepers use because they are efficient and easy to set up apart from being inexpensive.
Otherwise, acrylic or glass containers are very well-loved by fish keepers. To save money, some make use of sumps or even their old aquarium to create a new water reservoir. Good news for you: most storage reservoirs could be hidden inside your tank or behind the furniture to provide you with a compact set-up.
However, in case you want to fill a very large tank, you should go for a bigger container, for example, a big polyethylene tank or trash can, as the amount of evaporated water will be more significant than a small or medium sized aquarium.
The most important component – Sensor
It is very true to say that a sensor plays a key role in the performance of an Aquarium Auto Top Off System. To meet the different requirements of customers. manufacturers have produced a wide variety of products in general and sensor in particular that apply different methods to detect the lost amount of water.
To help you have a general view about this item, today we will introduce you 4 main types of sensors on the market which are an optical sensor, conductivity sensor, temperature sensor and float switch.
Without moving parts, an optical sensor is produced in the shape of a prism that helps the machine avoid a risk of failure. Also, an infrared LED light is used which glows through the prism and is led to something called light receiver.
- If there is no water, your pump will get activated after the light is led into the receiver
- If the rise of water level is detected, the light will be refracted passing through the water. Next, the little light will be headed to the receiver, and your pump will stop working
Another kind of sensor is the conductivity sensor. In fact, it takes advantage of 2 probes which are set as the standard water level. An electric circuit will be made immediately when the probes into the water to get the pump deactivated. Nevertheless, if the water is below those standard lines, that circuit will be broken right away to make the pump do its job.
Additionally, the conductivity sensor is made without moving parts to avoid the possibility of failure.
As its name suggests, the temperature sensor will make use of the heat to influence the pump. The user will install a probe inside the tank so that it is immersed in water. Once the water is below that probe, the heat will be generated quickly to make the sensor gets warm causing the pump to be activated.
Similar to the optical and conductivity sensor, this is produced without any moving parts to maximize the accuracy of the result.
This original sensor is the one and the only type to be produced with parts. If you have to buy a product on a tight budget, the float switch would be a good choice because it is effective and cheap. A buoyant magnet is utilized to close and open a circuit when the magnet moves along the water level.
This sensor is quite easy to get stuck since small animals can enter the float and some substances like calcium sometimes can be obstacles to magnet moving freely. Therefore, to avoid failure, most companies have made backup floats or plastic shields.
To be honest, even you purchase a pricey sensor or a cheap one, keep in mind that you must always keep it clean and clear of the blockage. All of them require monthly maintenance to make sure that everything is functioning well.
The last component in the list today is the pump as it will bring fresh water from the reservoir into your tank. Several systems come with a pump while others do not include it for a custom purpose.
There are 2 types of pumps on the market for you to choose – submersible and dosing pump.
- A submersible pump can be immersed into water and quickly transfer fresh water from the storage into your tank. It is very user-friendly and not expensive at all. Also, the submersible pump is accepted by most Auto Top Off Systems which do not have a pump included
- A dosing pump can help you prevent the dry-run. This pump will transfer water slowly to avoid the overflowing in contrast to the submersible pump. Instead of sinking into the water, it needs an external mounting above the water container
How to set up an Aquarium Auto Top Off System?
Another common concern about this item is how to set up an Auto Top Off System to make it work properly. Before going to the detailed guide, let’s watch a video about the basic installation.
Here are necessary steps that you need to take to set up an Aquarium Auto Top Off System:
- Make sure that you read and understand the instructions thoroughly in advance because each product has its features that you should pay attention to. It is also a nice way to avoid irreparable damage
- Before setting everything up, you had better check each item, especially the pump and the sensor carefully to see whether it works or not. You can skip this step if you want but how long will it take you to take everything out in case you get it done, but something does not function?
- Have an empty water reservoir since it is for safety reasons and honestly, it is much more challenging to work with full container
- Your water reservoir should go with a small opening to prevent the evaporation. On that lid, just drill a hole that is big enough to let the tubing go through. Again, do not make a big hole as the water will evaporate quickly
- There will be 2 sensors coming with your machine, and both of them need immersing into the water. One will be placed inside your tank, and the other will be installed into the reservoir. Please see to it that you strictly follow the manual instructions since sensors are the most important items when it comes to an Auto Top Off System
- There are 2 outlets that you will see in the pump – ‘in’ and ‘’ Connect the tubing to the reservoir to the ‘in.’ After that, run the other tubing from the ‘out’ to the sump in your tank. Ensure that you do not let your pump sink into water because it will suck the water to the water container
- Before plugging your machine make sure that the outlet is away from the water and your hands are completely dry for safety reasons
- Fill the water container and let the system do it job!
You might think it is too complicated when reading all those steps but trust me the installation is easy and will not take too much time.
What should you consider when buying an Auto Top Off System?
As I mentioned above, in today article, you will see how to choose the best Aquarium Auto Top Off System which can suit your demands by considering these following factors before making a purchase.
How large your tank is?
A lot of customers do not check the size of their aquarium before they buy a system. Why do you need to know the capacity? The reason is simple. It will help you pick the appropriate water reservoir as well as the pumps. A very large tank should not go with a 5-gallon container or weak pumps as it will take a lot of time to refill your reef tank.
What does that box offer you?
Well, in other words, you had better how many and what kinds of items you will receive after payment. A full package will have:
- Self-leveling controller
- 2 sensors
- Manual instructions
In some situations, you might get your water container or the pumps already, so find or ask the sales clerk the kit that does not include those accessories. However, if you do not have anything, a full package comes highly recommended since it helps you save tons of time when installing.
Is it easy to set up?
The ease of installation is another important contributing factor. It will be fine in case you are familiar with the technical stuff, but to those who never touch these things, it might be a big problem in case they accidentally pick a product that is too complicated. Systems which are equipped with magnetic mounts should be taken into consideration.
Does it work well?
Please ask the salesman to check the performance of your preferred system, particularly the sensors, before bringing it home. If they are not good at detecting the levels of water, your tank can get dry, or the water might be over the floor if your sensors are not sensitive enough to realize the lost amount of water or it is increasing too high.
How much can you afford?

|2||API AQUARIUM SALT Freshwater Aquarium Salt 16-Ounce Box||$6.79||Buy on Amazon|
There are thousands of choices for you available in the market. Thus, do not spend too much money on a pricey system. The most expensive one cannot guarantee that it will satisfy your personal needs. Hence, set your budget and find the system which you can easily afford.
