Zoo Med Turtle Clean 318 Submersible Filter – Review

The Zoo Med Turtle Clean 318 Submersible Filter ensures a clean environment for your reptile friends, and is best suited to work under the surface of the water. It comes with double inlets and removable cartridges that are easy to change.

A turtle is widely considered a docile and beautiful animal that is easy to keep and feed. Young children are big fans of these reptiles since they do not require much attention and are easy to maintain. These friendly creatures feed once a day, thrice or four times a week. Sounds easy, right? It is, but it is important to clean the environment in which they live.

Turtles have the tendency to mess their environment quite fast. They love to be in water, and they eat, sleep and excrete their waste in this same water. For this reason, the water in the tanks gets cloudy and smelly if not frequently cleaned. Don’t worry, you do not have to keep taking your turtles out every so often to clean out the tank. While a water change is recommended at least once a month, it is possible to maintain quality of the water if you use a good filter.

Zoo Med’s submersible filter is a device that works from beneath the water surface to rid it of food particles, chemicals and any unwanted microbial residue that might be in the tank. The Zoo Med Turtle Clean 318 Submersible Filter can work in tanks that have a capacity of up to 30 gallons. It can also be used in shallow tanks, as it can be installed horizontally.

What to expect from the Zoo Med Turtle Clean 318 Submersible Filter

This filter comes with several parts, each with a different function. The main filtering components are two sponges and activated carbon. One of the sponges is a long rectangular piece intended to sieve out food particles and other solid waste such as faecal matter that is in the water. The other sponge is a small square piece that traps microorganisms present in the water, and helps to balance the microbial population. It is placed in a small white cartridge that also houses activated carbon whose purpose is to rid the water of unwanted chemicals, especially nitrites that build up from waste deposited by the turtles.

The device also has a valve that you can adjust to regulate the flow of water to either of two settings, minimum or maximum output. There is also a detachable water diverter that channels the water in the desired direction. To secure the pump in place, you will use rubber suction cups that are included in the packaging. They provide a firm hold and prevent the filter from slipping out of place every now and then, especially where it is installed vertically.

The filter also comes with a manual that will guide you in the assembling, disassembling and cleaning practices. It is important to note that the directions are self-explanatory, and you will not encounter many technical terms.

Top 3 Features of the Zoo Med Turtle Clean Submersible Filter

This filter is a unique device that will set you at ease as far as a safe environment for your reptile friends goes. Here are its 3 key features.

It is fully submersible

This feature enables the filter to do a better than average job owing to the fact that the energy it requires to suck in the water is significantly low. This ensures that water flow is easier and faster, allowing for a more efficient filtering process. Being immersed in water also means you will not have to listen to your pump buzz on all day. The water acts as a noise cancellation medium.

It is a 3-in-1 filter

With this filter, you will not have to constantly fish out food particles, or change the water every so often owing to chemical and microbial build-up. The three main components ensure that all solid waste, chemical residue and microorganisms are efficiently eliminated. This mode of filtering contributes to the general health and well-being of your turtles, since harmful microorganisms such as fungi are removed from the water. Proper filtration also sees to it that you do not have to change the water in the tank every few days. With this filter, you will only have to do this once a month.

Easy assembly and disassembly

The Zoo Med Submersible Filter comes with an instruction manual that directs you on how to assemble and set it up. The device is built simply and you will likely be done installing it in a few minutes. This simple construction also ensures that whenever you remove the filter for cleaning, you will not have a difficult time putting it back together and re-installing it.

Since I was young, I have always had a thing for sea creatures. Being raised along the beach gave me the chance to interact with all kinds of reptiles, including turtles. I have always found this creature quite fascinating, and at a young age, I asked my parents to get me one as a pet. My love for turtles is what inspired me to pursue marine science when I got to college. Specializing in this field made learning so much about such reptiles. If you would like to get a pet turtle at your home, this guide will be of great help.
