Aquarium Leak Notifications with Wireless Water Sensors

Brian Hinderberger

An aquarium leak is a homeowner's worst case scenario; the water leaks onto its stand, your walls, and floor. Water damage from an aquarium can ruin the wood and potentially lead to dangerous mold within your walls and underneath your carpet or on the ceiling from an upstairs leak. 

Keeping the water inside a well-maintained fish tank is fairly easy but a faulty external filter or an undetected crack can spill a constant trickle to large amounts of fresh or saltwater onto your property investment. You need to take action quickly before the situation gets worse. 

You can avoid long conversations with your homeowner's insurance provider and save money from high-deductibles (that is if your insurance covers aquarium water damage). 

Presence Security Pack is your first defense to monitoring water leakage from your aquarium with your smartphone. Our wireless sensor comes along with the Presence Security Pack and you can order it separately to combine with your smart home security and protection.

Getting Presence Security is a smart move to protect your home and family.  Starting at only $199.95 and with no monthly fees required, Presence Security is one of the most cost effective and reliable security solutions available on the market.  

This sensor requires  Presence Security Pack  and is sold separately.
