ZOO MED™ Turtle Clean Filter 318 Tank Filtration System
Cheap because it's cheap.
Cliff notes: I would not recommend this filter to anyone. I was thrilled with the price at first. I opened the box, and it turns out the suction cups were not included... not a big deal. The filter was very quite upon startup. I had it in fresh, clean water for my baby red ear slider, but within a week the water was cloudy. I changed out the sponge and filtering "rocks" to no avail. Fast forward to about three weeks of use and weekly water changes due to the filter not actually filtering the water, and it started making a loud crunching noise. It sounds like the filtering rocks are trying to push themselves through the filter. The filter no longer works at all so I'm in the market for a new one. I probably would have been better off just changing the water in my turtle's tank every week than I would have been expecting this filter to actually do it's job.
