Step 1
Determine the filter style needed; you have two choices. One is an over the back filter. The other is a side entry filter. The style of turtle tank you own will determine the style of filter you need.
-
Step 2
Choose the filtration type. Filters have different types of filtration such as carbon or mesh. A filter that removes nitrates and nitrites is best for a turtle tank.
-
Step 3
Check the water flow speed. An adjustable water flow speed is best so you can adjust the current to your turtle's needs.
-
Step 4
Multiply your turtle tank size by three to determine the correct filter size. Turtles produce more waste than fish produce, so a larger filter is necessary for a turtle.
-
Step 5
Look at the extra features. Some filters have extra features such as a heater. Decide if you need the extra features.
-
Step 6
Consider the price value. A more expensive filter is not necessarily the best filter for your needs. Some prices are higher just because of the brand and not because the filter is any better than a less expensive one.
