What is the best turtle tank?
With so many good turtle tanks on the market, it can be hard to know where to start looking.
I struggled when I was looking for my first 100-gallon turtle tank.
What I’ve learned since then is that bigger is better – especially if your turtle (or turtles) have some growing to do.
After reviewing the many different options out there, we’ve narrowed it down to these 10 best turtle tanks.
We’ve included a range of tank sizes and price points. However, our top pick is the 150 Gallon SC Aquariums Tank– especially if you have more than one turtle.

What size turtle tank is best?
The most important question you need to ask when buying a tank for your turtle, is how big does it need to be?
The worst thing is to put a turtle into a tank that is too small.
The general rule of thumb is 1 inch of the shell to 10 gallons of water. Just measure the length of your turtle’s shell and, say it is 4 inches, you will need at least a 40-gallon tank.
However, also keep the following in mind:
- A turtle is best with a water depth 2.5 times its length
- You need room in the tank for a basking platform, which may tank up water space
- Your turtle will grow – it could be another inch longer within a year
- If there are multiple turtles in the tank you will need more space
Here are our 10 favorite tanks.
1. SC Aquariums 150 Gallon Starfire Glass Aquarium
After countless hours of research, we came to the conclusion that a larger tank is best for turtles.
So many pet turtles are kept in tanks that do not suit them.
Just think about how much space they have in the wild, and then imagine stuffing them into a 40-gallon turtle tank or smaller!
A 75 – 150 gallon tank is great for turtles, but as I’ve said, again and again, bigger is better!
The 150 gallon tank pictured above is from SC Aquariums, and it’s one of the largest that you can easily buy to have shipped to your home.
Larger tanks require special delivery options or to be picked up from the store.
- A good size for turtles (especially larger turtle breeds)
- Has a built in overflow box
- Removable black vinyl on back
- Good value for money
- More difficult to move and maintain
- Costs more than smaller tanks

Turtle Tank Buying Guide
We’ve already covered the best size tanks for turtles at the beginning.
Here are a few other things you need to consider when buying a turtle aquarium.
Some of these items are absolutely essential, such as turtle heat lamps, while others are not so important, such as a stand – unless you have a dog).
1. Turtle Tank Hood
All turtle tanks should have some type of covering or tank hood on top. Most come with a LED that mimics natural daylight.
Hoods also help protect your turtle from anything that may fall in, and it keeps your turtle from possibly getting out.
Some covers come with a locking mechanism to prevent curious turtles from pushing them off.
2. Turtle Tank Stand
Some turtle tanks work better with a display rack.
Placing your tank on a stand makes it easier to put it anywhere you want. Stands come in all sizes and designs.
Finding the right stand depends on the size of your tank.
3. UV Lights For Turtles
The right type of lights (example here on Amazon) can mean the difference between a healthy turtle and a sick one.
Turtles need to bask in the sunshine, and UV heating lights, LED strips, and reflectors are the next best thing.
Make sure you get these two types:
- UVA lights stabilize the mood and get it to eat right
- UVB lights help with the production of vitamin D3 for healthy bone and shell growth
4. Water Heater
The best water temperature should be between 74 and 82˚F.
Look for turtle tank water heaters that warm up the water evenly throughout the entire tank.
Use a thermometer to make sure the water temperature is just right.
The following guide can help you find the best heater for your tank:
- Up to 15 gallons = 50 watts
- Up to 40 gallons = 100 watts
- Up to 65 gallons = 150 watts
- Up to 75 gallons = 300 watts
5. Basking Platform
Turtles can get sick and die if they don’t find a warm place to rest in the sun.
Basking platforms, or turtle docks, should also be warmed. They should be between 85 and 90˚F.
You can mount a heat lamp above this area.
Make sure to keep it at a safe distance to prevent your turtle from reaching it and getting burned.
6. Water Filter
As turtles move around the tank, they make a big mess.
A turtle tank water filter can help reduce the mess and provide a powerful supply of clean water.
Turtle Tank FAQ
Here are some of the most commonly asked questions about setting up and maintaining a turtle tank in the home.
Remember that different varieties and sizes of turtles have different needs.
How often should I clean the tank?
Turtles make a lot of mess, so you have to be vigilant when it comes to cleaning the tank and water.
In general, tanks should be cleaned once every 10 days. But it mainly depends on the type of filter you’re using.
Between each cleaning, remove any large particle floating around daily. Each week, check to make sure the water is pH balanced, or between 7 and 8.
You should also replace the water, at least partially, to maintain its level.
How much water does my turtle need?
A good rule to follow is for every inch of your turtle’s height, you should provide at least 10 gallons of water.
Can I use tap water to fill the tank?
In most cases, it’s safe to use tap water.
But to be safe, check the pH value of the water to make sure it doesn’t contain any chlorine or other harmful chemicals.
