Do I really need a Filter for my Turtle Tank?
You absolutely do need to invest in a filter for your turtle tank.
A lot of people have a misconception that turtles aren’t as messy as fish and they can clean the tank on their own without investing in a filter. That’s all this is though; A misconception.
In fact, turtles are even messier than fish and require a filter that’s usually more powerful than a fish tank filter in order for the turtle tank to be effectively clean at a reasonable rate.
After all, turtles are living, breathing creatures that require oxygen and produce waste. Thus, there needs to be a system in place that is able to keep their environment clean so that they are able to breathe and live easily.
What Should I look for when Buying a Filter for my Turtle Tank?
Just like when buying a fish tank filter, there are several factors that you need to keep in mind when going out to buy a filter for your turtle tank. These factors are:
The most important thing you need to consider is how big your turtle tank is.
If you buy a filter that is too powerful for your small turtle tank, it will create strong currents in your tank and ultimately, make it uninhabitable for your turtles.
If you buy a filter that is too weak for a larger turtle tank you have, it won’t be able to clean the water at an effective rate.
So, it is very important that you look into what operating capacity the filter you’re buying operates at and to make sure that it will be able to clean your turtle tank at an appropriate rate.
No one wants to spend their hard-earned money on flimsy products that will break down over the course of a few months.
When you’re buying a filter for your turtle tank, observe the material it’s made of and ensure that it will be able to last for a long time in the conditions you have in your home or in your turtle tank in the case of an internal filter.
Most filters are made of plastic but that’s fine. What you need to observe is how strong and hard the plastic is. Usually, the most durable filters have a body made of hard plastic with many small parts made of metal. This makes them long-lasting and sturdy.
Type of Motor
The motor is the heart of the filter and you need to make sure that you’re getting one that has a motor that can serve your needs.
Depending on the type of construction, some motors don’t need any maintenance at all while others are extremely needy. You need to keep this in mind if you’re not going to have time to clean the motor regularly.
Also, if you’re not a big fan of humming or ambient background noise, you might want to invest in a filter that has some sort of noise suppression system built into the motor for quiet operation.
What are the Different Types of Filtration and is it necessary for my Filter to be able to do all of them?
There are mainly three types of filtration processes and yes, it is necessary that your filter is able to perform all three of them in order to be a well-rounded filter for your turtle tank.
The three main types of filtration processes are:
This process takes out any undissolved large particles in the tank water such as substrate residue, solid dirt and food leftovers. It does this by passing the water through a sponge or filter floss.
This process uses activated carbon to neutralize any harmful toxins and chemicals that might be present in the tank water.
Biological filtration optimizes the nitrogen cycle which encourages the growth of beneficial bacteria within your turtle tank. This boosts oxygen generation and makes the turtle tank a much more pleasant place for your turtles to live in.
What are some types of Filters I should avoid?
If you’re getting a filter for a turtle tank, we strongly recommend that you look towards the external canister or internal filter options.
Do not, under any circumstances, go for an under-gravel filter. Turtles are inquisitive creatures that like to mess with the gravel and substrate at the bottom of their tank. If you go out and invest in an under-gravel filter, you might end up in a situation where your turtles are messing about with the equipment and making it stop working or maybe even harming themselves in the process.
Should I get an External or an Internal Filter for my Turtle Tank?
Both external and internal filters have their pros and cons.
External filters are usually more expensive as they are larger and are able to work in bigger turtle tanks more effectively. They can be quite big in size and difficult to handle but they are quite powerful and get the job done.
Internal filters are relatively lightweight and less expensive. They are usually a great option if you have a smaller turtle tank that you would like to keep clean.
Do I have to invest in a more powerful Filter if I increase the number of Turtles in my Turtle Tank?
Yes. If you increase the number of turtles in your tank, you might want to invest in a filter that works at a greater operating capacity as you will now have to account for twice the waste in the same amount of time.
Not only this, when your turtles grow after a certain period of time, they start producing more waste. So, you might even have to change your filter and upgrade to a bigger one after some time even if you haven’t bought more turtles for your tank.
Frequently Asked Questions (FAQs)
How do I Set up a Canister Filter for my Turtle Tank?
External Canister filters are a little more complicated to set up than internal filters as internal filters just need to be mounted and you can just plug them in and they start doing their job.
Canister filters, on the other hand, come completely disassembled in their box. You have to carefully follow the instructions given with them in order to assemble them into a single module that can then be mounted onto your turtle tank.
Connect all the tubes and power cords. Double-check to make sure everything is securely connected and then turn the power on.
What type of Filter is best Suited for a Turtle Tank?
There are several factors that determine what kind of filter could be best for your specific turtle tank such as tank size, flow rate, type of motor, etc.
Normally, the biggest determining factors is the size of your turtle tank. A lot of people choose internal filters over external filters simply because they have smaller turtle tanks that do not need the high performance power of external filters.
Can I just use a Fish Filter for my Turtle Tank?
Yes. Most brands build their filters to be highly versatile so they can work in many different kinds of environments.
However, if you do plan on doing this, make sure you properly research the product you’re getting in order to ensure that it will be able to clean your turtle tank effectively within a reasonable time.
How regularly should I clean my Turtle Tank Filter?
Different filters come with different schedules and timelines that they require you to clean and maintain them. Like you may have noticed in our reviews, some filters required little to no maintenance at all while others were a bit more needy. Be sure to research your filter in order to know how often you need to perform maintenance on it in order to ensure there is no clogging, leakage or dirty tank water.
My water is starting to have a Green Tint to it, what’s wrong with my Filter?
This is due to an annoying kind of algae known as “Green Soup” algae. This algae breakout tends to happen when a new filter is installed and the turtle tank is not “cycled” properly.
Cycling refers to the process of letting the turtle tank breathe in its natural environment without any living creatures in order to encourage the growth of beneficial bacteria that are able to remove toxins from the tank water.
If your tank water has developed this green tint, we suggest leaving the tank in darkness for 1-2 days. It should be able to fix your problem. If the problem persists, we suggest investing in a water-detoxifying agent which are readily available in the market.
Turtles are adorable creatures but they are hard to take care of. It’s very important that we don’t skimp out when buying equipment that is responsible for keeping their living environment clean and healthy.
In the end, our winner definitely has to be the Fluval Canister Filter. It’s an extremely powerful filter that can clean turtle tanks up to 400 gallons in size without breaking a sweat. It’s extremely durable, easy to use and clean, and works without making the slightest sound.
