No matter what type of turtle you own, your pet reptile must have a cozy turtle tank to call home. In this guide to turtle tanks, we're making a list of all the supplies you'll need to create your own turtle tank. And we'll answer a few FAQs along the way to ensure your pet gets the best turtle tank possible.

We've Rounded Up Everything You Need to Set Up a Turtle Tank

Reptile Tank

First things first, you'll need to purchase the turtle tank itself. Turtle tanks are similar to fish tanks, usually varying between sizes and accessories. You'll want to do a little research before making a purchase to ensure you get the correct size and style for the turtle species you own.

What Size Tank Do You Need For A Turtle?

The minimum tank size you need depends entirely on the size of your pet turtle. But in general, the bigger the tank, the more space, the better. As a general rule, you should have at least 10 gallons of water for every one inch of shell length.

Smaller species require at least a 30-gallon tank, and larger turtles will need a tank that's upwards of 75 to 125 gallons. If you've purchased baby turtles, smaller aquariums can accommodate them, and you will need to upgrade to a larger tank as your turtle grows.

The red-eared slider is the most popular pet turtle in the United States. If you are thinking of getting one or already have one, the best tank size is between 20-50 gallons depending on the age. Full-grown turtles require large tanks of a minimum 50-gallon water tank.

What Kind Of Tank Does A Turtle Need?

Due to their durability and versatility, glass or acrylic are undoubtedly the most popular turtle tank materials. Turtles spend most of their time in the water, so you'll likely want an aquarium with a screened top.

Filter

Aquatic turtles spend a good deal of time in the water. A strong filter will keep your turtle's tank clean and ensure they've got a healthy space to swim around. The most popular styles are a canister filter or an internal aquarium filter.

Do Turtle Tanks Need A Filter?

Water filters are essential to the health and well-being of your turtle. They're notoriously messy animals that produce a lot of waste. A heavy-duty filtration system that helps remove bacteria and toxins for a healthier, happier pet is essential.

Heater

Next, you'll want to add a heater to keep your aquatic friends nice and cozy. In addition to keeping your pet comfortable, keeping an ambient temperature helps improve your turtle's health. The water temperature should be kept around 72-77 degrees F, and the basking spot should be between 85 to 90 degrees F.

Do turtles need heaters?

Turtles are cold-blooded, so you'll need to provide an external heat source to keep them warm. Aquatic turtles need both a water heater and a basking heater for adequate temperature regulation.

Light

Turtles need both UVA and UVB light to stay healthy. Like humans, they need the sun's rays to produce Vitamin D and absorb calcium. It's essential to provide your reptile with a comfortable place to bask in a warm light.

Should I Leave My Turtle's Light On At Night?

There's no need to keep your turtle's light on overnight. Most turtles will bask for several hours each day. Some will need between 10 to 12 hours of UV light per day, so they'll be just fine in the dark for a few hours. In fact, turning the light off at night helps recreate a natural environment.

Decor

Unlike other reptiles and amphibians, your turtle tank should stay relatively sparse. Turtles are known for destroying tank decorations and turning unnecessary substrate into a waste-filled mess. Remember, the more complex your tank is, the more laborious it will be to clean.

What Do Turtles Like In Their Tanks?

The best tanks offer your shelled companions plenty of space to bask, splash, eat, and rest. At a minimum, your turtle needs some gravel or sand, a few driftwood pieces, a pool, plants, and a basking platform. Because turtles can be pretty destructive, stick mainly to tank decor made from natural materials instead of plastic that's potentially harmful if swallowed.

Best Decors To Add To The Tank

Plants

To add a natural flair, you can add java ferns, java moss, anubias, and anacharis. If you are going to add plants, opt out of artificial and opt-in on real plants.

Water Treatment

Your tank needs to be filled with enough water so your turtle will not drown. There should be enough water for your turtle to rotate, dive, and totally submerge. Your aquatic turtle's water should also be treated with a water conditioner and tested for ammonia and nitrite levels regularly.

Using water conditioners in your water will help keep your pet safe, healthy water to drink and soak in. It will remove chlorine and other contaminants from tap water to keep your turtle tank clean.
