Instructions
Choose a tank that is large enough for your turtle and won't be crowded if you have more than one. A 25-gallon tank is a good start for one turtle, but consider a 50-gallon tank if you plan on having two or three and don't want to buy another tank later.
Add water to the tank that is at least as deep as the turtle is long. According to PetTurtleCareGuide.com, this helps the turtle to get in and out of the water more easily.
Place large rocks or floating turtle platforms in the tank. Strategically placing stationary rocks on the ends allows the turtle plenty of space to swim.
Install a water heater and filter to keep the water moving, clean and the ideal temperature for your turtle. Check your local pet store for filter-and-waterfall or filter-and-heater combinations that reduce the space these accessories utilize.
Place a waterproof thermometer in the water. Turtles need the water to remain at 75 degrees. Adjust your heater as necessary to keep the ideal temperature for your turtle.
Place a lamp at the top of the tank. Many lamps clamp to the top of the tank, while others straddle the width. You may choose between a heat, UV or fluorescent lamp to provide your turtle with the white light needed to remain healthy. Situating the lamp directly over a basking rock is ideal.
How to Assemble a Turtle Tank
Turtles are quiet, intriguing pets for children of all ages. While it may seem easy enough to put some water in a tank and give the turtle a rock to bask on, turtle care is much more involved that that. Improper tank maintenance can lead to serious health issues for your turtle and anyone handling him. Part of keeping everyone healthy is setting up the turtle habitat properly in the first place.
