Whether you have a snake, lizard, turtle, or other type of reptile, it's always smart to use treatment products for their water. The chemical treatment of tap water, which makes it suitable for human consumption, leaves toxic residues of chlorine and chloramine in the water. Minute traces of toxic metals also make tap water unsafe to reptiles and amphibians. Always treat tap water with Aquatize terrarium water conditioner. Aquatize contains plant extracts to stimulate natural slime coat development in amphibians and fish. Essential oils in these extracts promote shedding in reptiles and maintain scales and skin tissue in optimal health.

• Makes tap water safe, for healthier terrarium water conditions
• Removes Chlorine & Chloramine
• Neutralizes heavy metals
• Stimulates slime coat development in amphibians & fish
• Shedding aid
• Ideal for use in combination with Exo Terra Turtle Clean Biological Turtle Habitat Cleaner

Reptiles are ectothermic and use heat from an external source to thermoregulate their optimal body temperature. Most reptiles use direct radiant heat from the sun in combination with conductive heat from sun-heated surfaces such as branches, rocks or other heat accumulating structures.

Providing such an appropriate, species related, temperature gradient in the terrarium is an important factor in successful reptile keeping. With the Exo Terra 300 W Electronic ON/OFF Thermostat you can create a well controlled heating system that allows you to maintain the required temperature conditions similar to those found in a desert or tropical environment. The Thermostat will also help to prevent overheating and under-cooling during hot summer days or cold winter nights.

The electronic Triac switch keeps the temperature at the desired set point with a much higher accuracy compared to conventional thermostats and virtually eliminates temperature swings in the terrarium.

Simply connect your Heat Mat, Heat Cable or Ceramic Heater to the Exo Terra ON/OFF Thermostat, set the preferred temperature and place the heat sensor in the desired spot. The Red LED heat indicator will light up when the heating device is ON and will shut off once the desired temperature has been reached.

The recessed dial of the thermostat will prevent accidental temperature change if the device is being handled. The waterproof remote sensor can be safely used in highly moist terrariums and aquatic environments.

The Exo Terra Thermostat should be set according to the needs of the animals. Thoroughly research the preferred optimum temperature range (POTR) for your specific reptile, so you can create the correct temperature gradients inside the terrarium to allow your reptiles to thermoregulate.

• Accurately controls terrarium temperatures
• Ideal for use with Heat Mats and Heat Cables
• From 20°C up to 35°C (68°F - 95°F)
• Waterproof remote sensor
• Controls heating devices up to 300 W

The Exo Terra Stone Desert mimics the natural soil found in arid regions, like deserts or savannahs. Most desert soils are not purely sand-based but rather a combination of sand, decomposed granite and clay resulting in interesting and sometimes colorful rock formations.

Exo Terra's Stone Desert allows you to create your own desert or savannah landscape, including cool-humid burrows as well as warmer elevated basking areas. The cool-humid burrows allow your reptiles to absorb the much needed moisture via their skin while sleeping or hiding, while the warmer elevated basking areas help your reptiles to thermoregulate by offering various important temperature gradients.

• Natural desert soil, no added dyes or chemicals
• Ideal to create your own desert or savannah landscape
• Allows you to create outcrops, tunnels and burrows
• Stimulates natural digging and burrowing behavior
• Does not collapse once dry
• Excellent heat conductor

Available in: 10 kg (22 lbs)

The Exo Terra Reptile UVB200 VHO T5 Bulb delivers medium levels of UVB radiation to replicate semi-shaded or partially sunny habitats, making it ideal for occasional baskers and reptiles that move between sunlit and shaded areas. With a 7% UVB output aligned with Ferguson Zone 2 and the Mesophotic Zone, it supports healthy vitamin D3 synthesis and efficient calcium metabolism to help prevent metabolic bone disease (MBD) while encouraging natural basking behaviors. Featuring Exo Terra’s advanced Sunergy™ phosphor blend, developed with German precision technology to closely mimic the sun’s UV spectrum, this T5 lamp produces highly effective UVA and UVB emissions with greater penetration than traditional T8 bulbs, making it suitable for taller terrariums or those with dense screens. Designed for seamless use with Exo Terra T5 fixtures and compatible with standard T5 holders, it provides reliable, biologically effective UVB output for up to 12 months. By establishing a proper UV Index gradient, from higher levels at the basking area to shaded zones with little or no UV, reptiles can safely self-regulate their exposure.
