Another element of heating Red Eared Slider Turtles Trachemys scripta elegans is that of heating the water. There is really only one way to heat the water and that is through the use of a submersible aquarium heater. If you actually purchase a “turtle tank” which has an area cut into the side of it for the filter to hang on you could theoretically use a hang on the back heater but I don’t recommend these as with an active turtle they can be knocked off potentially causing a shock hazard.
Submersible aquarium heaters are the best ones to use but I have heard of turtles actually breaking these as well. To prevent this you can buy a submersible heater guard which is relatively inexpensive. You can also take a piece of schedule 20 PVC pipe and drill a bunch of holes into it and then slide this over the heater as well. Personally, I have never had an issue with turtles breaking the heaters I have used, but to be on the safe side I would recommend using the heater guides.
Filtration for turtles is a subject too often overlooked by most new turtle keepers. No doubt this is due in part to most pet shops using a filtration system that is hidden from public view to make the environment more appealing. Therefore people presume one is not needed. Also if the buyer is purchasing one of the turtles from an illegal source such as a swap meet or flea market then they are usually presented in small habitats which have no filters in the first place. So it is easy to see why the filtration is overlooked by the public. Add to this that most retailers are focused on the sale and not the actual long term care they do not mention filtration as filters tend to be one of the more expensive parts of the habitat. Next
