In the event of a power outage, is your tank protected?

This product is for any serious aquarium hobbyist that wants to protect his or her investment in the case of a power outage. In 4 - 6 hours of no flow within an aquarium can can cause the death of valuable fish and corals. Extreme weather can strike at anytime, and we can’t always predict the outcome. By adding the an IceCap Battery Backup, your tank’s flow will continue for up to ~35 hours after the power goes out (~17 hours for two pumps). Add a second battery backup to double the run time.

Hook your Maxspect Gyre pump to the IceCap Interface module will automatically detect when main power is lost and will slow the gyre the 30% speed to extend the life of the battery. The module is backwards compatible and will run gyres already on the market.

The red LED will blink 2-5 times and repeat. 5 blinks 100% power - a reading of 12volts of power 4 blinks 80% power- a reading of 11-12 volts 3 blinks 60% power- a reading of 10-11 volts 2 blinks 40% power- a reading of 9-10 volts 1 blink 20% power- Less than 9 volts and the pump will soon quit working.

I had a UPS designed for a computer as a back up, but the first time it was needed in a power outage I got an error and it failed, I bought the ice cap to power my gyre pump to keep water flowing in case of a future outage. It arrived very fast and was very easy to install. Followed directions and had it hooked up and running in less than 5 minutes. It is a very cheap "piece of mind" for all I have invested in corals. Great Idea and it is supposed to give me about 35 hours of run time if needed.
