Turtles are the silent and peace-loving aquatic creatures with a long life and yes, frequent bowel movements. Often people think that keeping a turtle is not tricky as these lazy creatures will quietly swim in the tank, won’t need constant attention or pampering and are low profile (I wish that were the case). Let’s break your bubble and enlighten you on the subject of turtle habitation.

Turtles can be messy and need a clean habitat to haul out and bask. It is one of the reasons why turtle tanks are large and do not have fish in it. Like other organisms and humans, even turtles need space. Ideally, a 30-gallon aquarium with clear glass is perfect for a turtle as they are active swimmers and love to bask around.

However, if you have bought a turtle that can grow more than 8-inches, then you need a tank with 75-125 gallon capacity. Also, there is a threat that they may carry salmonella that can be transmitted to other aquatic animals; that is why you should abstain from stocking the tank.

Feeding a turtle is not easy. They like to have a variety of food, including mice, crickets, snails, worms, fruits and plants. So, you need to feed them according to their nutritional requirements that change as they mature. When it comes to hygiene and maintenance, turtles need fresh and clean water.

It is ideal given the fact that it will be dirty with its discharge as well as the plants and food you put in the tank. Manual cleaning can be tedious and time-consuming, especially when it has to be done every fortnight; this is where an equipment like the best Filters for Turtle Tanks come in the picture. But sadly, most people are not aware of the benefits of filters, let alone the best filter for turtle tank and how they can make your life easy.

Why Do You Need A Filter For Your Turtle Tank?

Be it for good luck and wealth or because you simply adore these peace-loving creatures, if you plan to buy a turtle, then you should learn about their accommodation and hygiene requirements.

Most people are not aware that turtles can make the tank dirty faster than a fish, and you may need to change water frequently. But, the smart way to deal with turtle excrements and debris is using filters. A filter will help in keeping the water clean, which is a basic necessity and the first point in the turtle keeping tutorial.

A sound filtration system will help in keeping the tank clean, and you can delay the water changing process. Rather than manually cleaning the tank and changing the water, a filter will do it for you and make your life easy.

Often as a turtle owner, you will have to spend one hour every day on its cleaning and upkeep including clearing out debris and unclogging the area. With a filter, you can outsource the chores that will clear out everything through a mechanical, chemical and biological process.

Now go on and purchase the best filter for turtle tank that will clean the tank and keep your marine friend healthy. It will also help you save time and energy in cleaning the tank manually every fortnight. If you are confused about which filter to opt for, canister or internal filter, then check-out the below-mentioned factors to make the right decision.

Factors To Look For When Buying the Best Turtle Tank Filter

What should be the flow rate of the filter? Is a 30 gallons capacity enough? Should I opt for an external or internal filter? Is one filter enough or should I use two for a large turtle tank? These are the questions that can confuse a newbie, especially if you are planning to shop online.

Certain essential factors can distinguish an average filter from the best turtle tank filter and will make keeping an aquatic buddy an enjoyable task with minimal responsibility. So read on and get a filter that is turtle and tank friendly:

1. Species Of The Turtle

This is the most overlooked factor, but the most crucial as well. How can you find the best filter for turtle tank, if you don’t know the species of the turtle? Every turtle is different in carapace length, bowel movements, basking time and space requirements. We also know that turtles excrete more than fishes resulting in foul odour, discoloration, and a dirty tank.

Now, if you have a small tank and you place a filter in it, it will take up most of the space, causing discomfort to your aquatic friend. Also, keep in mind how many turtles you want to stock, if you are opting for two turtles then you need a filter with more capacity. So, it is essential to know the species of the turtle and accordingly decide whether you need an exterior or interior filter.

2. Type Of Filtration System

Turtles are going to spend most of their life inside an aquarium swimming in their own discharge. So keeping the tank and water clean is essential to ensure that your turtle gets a hygienic habitat. Also, we need to know how often we should change the water, and it depends on how many aquatic animals we have stocked in the aquarium. More the number of turtles or other animals more waste accumulation. Thus, you need to change water frequently.

We also need to choose between an external canister that allows space for the marine pets and is easy to maintain and powerful internal filters. Another factor to consider is whether the tank needs two-stage filtration, i.e. biological and mechanical, or three-stage filtration, i.e. mechanical, chemical and biological. In my opinion, three-stage filtration system works the best.

3. Size Of The Tank

The size of the tank and capacity of the filter are directly proportional to each other. If you have a large tank and there is a variety of aquatic animals, then you need a filter with a capacity of 95-120 gallons. Similarly, if you have a turtle that can grow up to 6-inches, then you need a tank with 50-gallons capacity as turtles love to swim and bask. But, if you have a single turtle in a medium-sized tank, then anything above 30 gallon capacity will work. Also, you may have to keep two filters if you have a large tank housing both marine flora and fauna.

4. Brand

If you are a brand conscious person, then better purchase from an established brand as they are cautious about their brand reputation. They have the resources to experiment and launch the best filter for turtle tank in the market as their reputation is at stake.

There is a reason canisters are considered a classic, and still, people prefer to opt for an old and established brand than to pick a relatively new brand. Also, they offer warranties, after-sales service, customer care service and other incentives that may not be the case with a non-branded filter.

5. Durability

You don’t want your filter to breakdown due to clogging or rough climatic conditions (which is the case with external filters), resulting in all your investment going down the drain. So, durability is a factor that can’t be ignored. Considering the fact that the filter has to operate regularly to clean water, wear and tear is bound to happen.

However, you don’t need that within a couple of weeks or just a few months after the purchase. Also, you need a filter that works for saline water as well and does not give away due to accumulation of salt. Therefore opt for a filter that is powerful and can work efficiently for saline and freshwater.

6. Maintenance Of The Filter

Chances of breakdown double if the filter is not clean and properly maintained. Maintenance of a filter should not be a herculean task. But if the filter is attached to too many cables and hoses or cannot be reassembled, then it will be an issue. The best filter for turtle tank is the one that is self-sustaining and is easy to maintain.

So, opt for one that can be taken apart, cleaned and reinstalled. If you are looking for an internal filter, then choose the one that does not spill the liquid waste inside the tank the moment you pick it up for cleaning. Whereas, an external filter like a canister is easy to clean and won’t leak the waste in the water. So, again it depends on the type of the filter.

7. Filter Media

Cleaning of the turtle tank is done by the filter media that includes sponges, bio-balls, activated charcoal, polyfill, etc. Now there are few things that can be replaced like activated charcoal or polyfill, but sponges can be used for a long time. Most people use the same filter media for a turtle tank and a fish tank, but it should not be done.

Except for the basic things like sponges or filter bags, try to use filter media, which does not harm the turtles and also keeps the tank clean.

8. Flow Rate

Cleaning of the tank depends on the flow rate of the water. A faster flow of water will clean the tank quickly and won’t give time for the residue to settle down. It will also clean the tank at the edges or inside/behind rocks where a lot of waste is accumulated.

One should opt for a filter that offers an option to manually adjust the flow rate as it will give you the control. You can increase the flow when the tank needs cleaning else keep it neutral so that aquatic animals don’t feel the current.

9. Type Of Motor

What kind of motor does your filter require? You don’t need a motor that is noisy and difficult to maintain. Even the efficiency and longevity of the filter depends on the motor. It is often observed that the best filter for turtle tank will have a strong motor and won’t require regular repair or maintenance. A responsible manufacturer will work on the motor and provide clear instructions on how to keep the motor clean and running.

10. Price

It is a personal factor and depends mostly on your spending capacity. But, one should not compromise on a filter for the turtle tank as you are responsible for a life. The need for clean water and a basking area cannot be stressed enough. Hence, quality should not be compromised.

Investing in a quality turtle tank can be expensive, but it is a one-time investment. An asset is created that will keep your aquatic friend healthy and comfortable. So, opt for a brand that might stretch your budget a little but can serve you for a long time with minimum repair and maintenance issues.
