Maintaining proper hygiene should be the top priority for all turtle owners. Commercial filters offer the best service to keep the water clean. But which filter model should you buy for your indoor turtle pond?

You can check the Fluval 7 series Canister filters for the small and medium indoor turtle ponds. Marineland 360 and SunSun HW303B also suit ponds up to 100 gallons. You need a powerful filter for ponds above 200 gallons. Fluval FX6, PondBoss, and Beckett filters have quite a name for large pond filtration.

Which pond filter model should you buy? How can you select the filter model? I will answer these in the following article.

Key Takeaways

  • Average Canister filters can maintain the hygiene of small and medium ponds.
  • You need a powerful filter for large indoor and outdoor ponds.
  • A pond with multiple turtles, fish, and live plants needs a strong filtration system.

Which Is The Best Indoor Turtle Pond Filter?

The filter size, capacity, and model will solely depend on the setup and the pond size. Indoor surface-mount ponds can be,

  • Small (45 to 60 gallon)
  • Medium (60 to 150 gallon)
  • Large (150 to 800 gallon)

Of course, the small and medium pond tubs are most suitable for indoor setups. These ponds can easily accommodate hatchlings and young turtles. In fact, medium-sized adults will swim effortlessly in these tubs.

Well, you can go for the large ponds when you have a big adult turtle. However, spacious housing is necessary to raise multiple turtles, too.

From my experience, I have learned that the large turtles thrive in outdoor ponds.

In the sections below, I will talk about pond filters of various kinds. I will also mention their filtering capacity. Select a suitable one by comparing this feature to your turtle pond size.

One friendly reminder. You do not need a pond filter for the small and medium turtle indoor habitats. The canister filters are enough to process such capacities.

Pond filters are designed to handle large water loads. Hence, they are suitable for large indoor turtle housings and outdoor ponds.

What Is The Best Filter For Extremely Large Indoor Turtle Pond?

Most owners keep their indoor turtle pond limited to 400 gallons. But of course, you can aim for 700 and even 1000 gallons if you have the space. However, you must buy a more powerful filter in such cases.

Generally, filters designed for outdoor ponds work smoothly with grand or extremely large indoor ponds. But most models do not come with an in-built pump like Canister filters. So, you may have to make a few electrical and space adjustments to fit the filters in, depending on the model.

Let’s explore your options.

1. POND BOSS Filter Kit with Pump

The Pond Boss is perfect for ponds below 500 gallons. Compared to other filters, this Pond Boss model is easier to install and maintain. Besides, the package comes with a pump. Hence, it is budget-friendly and more convenient.

Does A Turtle Need A Filter?

I have met owners who are not convinced to buy a filter for their turtle pond. As per them, these creatures just live fine without a filter in the wild.

But hey! There are natural currents in the streams and rivers. As a result, the water stays clean all the time. In contrast, indoor or outdoor ponds are artificial water sources and require daily cleaning. Otherwise, the poop and food leftovers will settle at the bottom of the tank and rot.

Remember, turtles are aquatic creatures. They spend 50 – 75% of their entire life in the water. So, it goes without saying how much the water condition matters to them.

The filthy water can cause skin and eye irritation to turtles. Besides, such unhygienic water entices bacteria and fungal growth. Hence, your pets may fall victim to serious infectious diseases. These turtles will be prone to shell rot and mouth rot.

Installing a filter will eliminate all these issues. The powerful pump of the filters takes in the filth and circulates freshwater efficiently. Besides, the built-in technology allows them to maintain a healthy pH inside the pond water. The latest filter models include bio-balls in them to promote good bacterial growth.

How To DIY A Turtle Pond Filter?

You have to spend a minimum of $90 for a turtle pond filter. This price rises to a minimum of $150 if you want a Canister filter for indoor ponds.

I understand if it is out of your budget. But of course, you can not just build the pet pond without a filter. Right?

In such scenarios, go for a DIY pond filter. Do these DIY projects work perfectly? If you can glue everything together, the filter should serve its purpose.

However, the build quality of the homemade filters is not top-notch. Hence, you may struggle to fit the device in the pond. Moreover, the filtration basket will have a shorter lifespan and require more frequent cleaning.

Nevertheless, in Canister filters and pond filters, the wirings are well-hidden. Any wiring mistake from your end can risk the turtles getting electrocuted.

Well, you can give the filter DIY project a try if you are confident enough. The steps are shown below,

  • Buy a pump according to turtle pond size and a container to fit the pump.
  • Drill a large hole in the container wall. Connect the pump to the water tube via this hole. You have to drill multiple small holes in the walls and lids to maintain the water pressure.
  • Take a net bag. Put bio balls, lava rocks, and carbonated charcoal in it. Then, place the bag beside the pump in the box.
  • Next, make a stack of quill pads and polyester fiber. Fill up the empty spaces inside the container with this fiber stack.
  • Close the lid, and your filter is ready to rock. Just place it at a suitable place in the turtle pond and provide an electrical connection.

How To Choose The Best Filter For Turtle Pond?

I have mentioned several filters suitable for your turtle’s pond. But of course, you can go with other brands and models if you find those suitable. You must consider several points when buying a filter for the pond. Such as,

1. Size And Elements In The Pond

Big turtles or a community habitat will create more mess. Again, adding fish or live plants will also increase the waste percentage in the water. Besides, ponds with more exposed sunlight develop algae more quickly.

Consider all the details in the pond when buying the filter. The more the element, the more powerful filtration is required.

2. Price Range

I am sure you have a budget in your mind for the pond filter. Shuffle through the brands and models until you find the right product. Do not compromise on quality because of money. If you are on a strict budget, a DIY project will help.

3. Filter Type

You will find box, Canister, and all-in-one filters in the market. Some of them are submersible, and others should be on the ground. Revise your pond design and select the filter type accordingly.

4. The Right Capacity

As per experts, the installed filter should be able to process half the tank water per hour. It means for a 400-gallon tank, set up a filter with a 200-gallon capacity.

5. Filtration Layers

The latest filters have a 3-stage filtration system. Such as, mechanical, biological, and chemical. Each of these layers ensures that no filth can pass to the freshwater. Try to purchase a filter that includes multistage filtration.

6. Installation And Maintenance

The filters should be easy to install and clean. For example, the one-finger media basket removal system is really amazing. Remember, you have to clean the filters once a few months. So, give priorities to those models which are easy to maintain.

Before You Go…

Buying a filter for the pond is not enough. You must change the water in the turtle pond and give it a thorough clean sometimes. I have discussed the scheduling details along with cleaning techniques in the attached link.
