Turtle Filter + Media

One Seaforia ST-01 internal low-water turtle tank filter with one pack of four matching replacement media pieces. Its compact vertical body sits inside the habitat and returns water through a waterfall outlet.

What comes in the turtle filter kit?

• One ST-01 filter unit.
• One four-piece pack of matching replacement sponge clips and filter boxes.

The four pieces are extra refills, not four filters or a guaranteed four-month supply. Aquarium, animals and decorative items are not included.

Will it work at my water depth?

Low-water operation still requires the correct working water depth. A numerical minimum for the current unit has not been confirmed here. Share your normal water depth, actual water volume, animals kept and mounting space with us before ordering for a shallow habitat. Check the supplied instructions and electrical label before connecting power. Never run the filter dry.

Check low-water filter fit or ask Seaforia about your turtle setup.

Setup, flow and routine care

Follow the ST-01 instructions for positioning, first use and priming where specified. Do not assume the adjustable flow control of the hang-on-back aquarium filter is present on this model. Disconnect power before removing or maintaining parts. Check the intake and media regularly; cleaning and replacement depend on the supplied instructions and your tank conditions.

Find the correct replacement media

Match the ST-01 label on your unit before choosing ST-01 four-piece replacement cartridges. SF-series and other ST-series packs are not assumed interchangeable.

Will it clear every kind of cloudy water?

No universal clearing time or algae-removal result is promised. Debris, milky cloudiness and green water call for different checks, alongside water testing and appropriate habitat care. Read the cloudy-water guidance. A filter light does not replace the basking and UVB lighting required by the species you keep.
