Usage and Maintenance

How Do I Use the Zilla Spring Cave?

The Zilla Spring Cave comes in three sections.

The base is the reservoir. Choose your cave location, place, and fill the reservoir as directed.

Place the internal cave section on the top and install the pump.

Ensure the pump is in the water. Hide any wiring in the back. Once in place position the top of the cave along with the feeding bowl.

Turn on the spring cave and allow for the pump to prime and start pumping water. Once it’s pumping you can add the stick to the front of the cave, offering easy access for your pet.

How Often Do I Need to Fill the Water?

How often you fill the water is determined by the humidity levels in the tank. The reservoir may need filling anywhere from one week to one month.

How Often Must I Clean the Zilla Spring Cave?

The cave will need to be thoroughly cleaned once a month. This means breaking it down, washing all the pieces and putting it back together again.

You may notice that the pump starts to slow as debris gets caught up in the pump. You will need to clean the pump when this happens to ensure it continues to run at optimal.

Unfortunately, to reach the pump, you need to dismantle the entire cave. For this reason, you may find yourself cleaning the cave once a week.

Can I Put Liquid Calcium in the Water?

Liquid calcium is a wonderful way to help your reptile get the calcium it needs to reduce the risk of illness.

Liquid calcium is added to your pet’s water source and can be used with the spring cave, though you will need to keep an eye on the water flow, cleaning the pump and changing the water may need to be carried out more regularly.

Can I Wash the Cave with Soapy Water?

You can wash the cave with hot soapy water, ensure you rinse thoroughly.

You will also want to dry wipe it a few times.

You will find even when wiping dry the paint comes off on the cloth.

You may need to wash a few times before the smell fades.

Ensure it is rinsed well with no soapy residue before adding to your terrarium.
