Exo Terra Turtle Pebbles Large 10–20mm 4.5kg Aquatic Substrate PT3833

ET Turtle Pebbles Large are smooth, naturally rounded river pebbles designed as a safe, realistic substrate for turtle enclosures. With a pebble size of 10–20mm and a 4.5kg bag, this is a practical choice for keepers setting up or refreshing a turtle tank where both aesthetics and animal welfare matter.

Natural Origin, Safer for Turtles

These pebbles have been naturally smoothed by fast-moving river currents over time, removing sharp edges and rough surfaces. That rounded finish is important for turtles that forage or rest on the substrate — it reduces the risk of shell and skin injury that sharper aggregates can cause.

Realistic Riverbed Appearance

The varied colours and natural patterning across the pebbles recreate the look of a genuine riverbed environment. This makes the enclosure visually cohesive without relying on dyed or artificially textured materials.

Size Guide

The large grade — 10 to 20mm — is suited to turtles with a shell diameter greater than approximately 10cm. For smaller or juvenile turtles, a finer grade would be more appropriate to avoid any risk of ingestion.

Cleaning and Reuse

ET Turtle Pebbles can be cleaned and reused rather than discarded. Soak them in a bucket of water with a suitable disinfectant for around 15 minutes, then rinse thoroughly until the water runs completely clear and no visible debris remains.

A straightforward, low-maintenance substrate that prioritises your turtle's safety and gives the enclosure a natural finish — practical for both new setups and established tanks.
