Buying Guide for Best Filter System For Turtles

Flow Rate

Flow rate is the amount of water that flows through the filter per hour. If your filter system's flow rate is low and the water in the tank isn't completely filtered, it can lead to illness and in the worst case, the death of your cute aquatic pet.

The flow rate will let you know that how many gallons of water can be filtered in one hour. It should be according to the size of your tank.

If you have a small tank, then you don't need a filter system with too much flow rate because tanks with high flow rates are pricy. In the case of a large tank, you need the best filter system that can clean the tank's water effectively with a high flow rate. 

Type Of Filtration

There are a lot of different types of filtration systems. When buying a system for your turtles, you need to consider what you want to use the system for and for whom you will be using the system. 

There are standard tanks and there are saltwater systems. You can also get a wet/dry filter and use it in the tank or in the pond.

Size of Tank

Look at the size of the tank and then compare it with the filtration system that you wanted to buy. If you buy a small filter system and the size of the tank is too much, then you won't get better results so look for its specifications and compare it with your tank's size.
