Do Red Eared Sliders Need a Filter?

Do red eared sliders need filter

The purpose of a filter in your red-eared slider tank is to remove waste materials like uneaten food and turtle excreta from the water before they harm your turtle.

Red-eared sliders produce copious amounts of waste throughout the day, which needs to be removed before it rots and releases toxic chemicals. If the waste isn’t removed it will result in a build-up of ammonia and nitrite which can harm a turtle’s health.

Turtle waste can also lead to odor problems that can make living with an unfiltered turtle tank unbearable. Most turtle filters also use activated carbon which can help control turtle tank odor problems.

A good turtle canister filter will also trap the waste so you can quickly and easily remove it without having to do a water change. This helps ensure that your turtle tank always has crystal clear water, and it will prevent any uneaten food from causing cloudy or green water.

 

 

What Kind of Filter Should I Use for My Turtle Tank?

Canister filters are your best option if you’re looking for the best filter for turtles. These types of filters have a high capacity that’s suited for turtle tanks since turtles produce a large bioload. They also are easier to maintain than other types of filters since they can be used with a wide range of mechanical, chemical, and biological filter media.

 

 

Why Does My Turtle Water Get Cloudy so Fast?

Why does my turtle water get cloudy so fast

Cloudy water is a sign of a bacterial bloom in your turtle tank. This happens in new turtle tanks when they haven’t been fully colonized by beneficial bacteria.

Cloudy water can also happen if you overfeed your turtle, or if you don’t have a large enough filtration system to process the water.

A new turtle tank will eventually stop getting cloudy water once the tank matures and develops a healthy colony of nitrifying bacteria.

 

 

How Do I make My Turtle’s Water Clear?

You can use API ACCU-CLEAR Freshwater Aquarium Water Clarifier (Buy Online) to quickly treat cloudy water. This will reduce the problem by causing the particulate to precipitate out of the water, but it won’t get to the root of the problem.

If you want to quickly treat cloudy water you can use a stand-alone UV sterilizer to kill the bacteria in the water, or you can use a canister filter with a built-in UV sterilizer.

If you still experience cloudy water in a mature turtle tank after a water change it might be because you’re destabilizing your turtle tanks water parameters. Make sure your turtle tank pH stays between 6-8, and treat your tank with enough water conditioner so you don’t kill off the beneficial bacteria in the filter.

It’s also a good idea to check your nitrate levels with a Water Test Kit (Buy Online) to ensure you’re tank isn’t filled with nutrients that can fuel cloudy water.

 

 

Do Turtles Like Dirty Water?

Do turtles like dirty water

Turtles are more tolerant of dirty water than fish, but they still need to be kept in clean safe water. In the wild turtles can live in muddy turbid water that we would consider very dirty. However, muddy water could be “clean” since it might have low levels of ammonia, nitrite, and nitrate.

While it might be tempting to let your turtle tank get dirty it’s a good idea to keep up regular maintenance for the health of your turtle. Also, you’ll want to keep your turtle tank clean since a dirty turtle tank can emit noxious odors.
