Fish and coral can start dying in as little as 4 hours without water flow, and a power outage doesn't care what time it happens - the IceCap Battery Backup v3.0 keeps a flow pump running through exactly that gap.
Why 4 Hours Is the Real Deadline
Without water movement, oxygen depletion and localized dead spots can turn dangerous surprisingly fast - a few hours is often all it takes to put a heavily stocked tank at real risk during an outage, especially overnight when no one's around to notice.
What the Battery Backup Offers
- Keeps a compatible flow pump running automatically when grid power drops, without any manual intervention needed.
- Bridges the gap until power returns or you're able to intervene manually.
- Version 3.0 reflects IceCap's refined design for this specific outage-protection role.
Setup Tips
- Confirm compatibility with your specific pump before ordering.
- Test periodically rather than assuming it will work correctly when you actually need it during a real outage.
- Pair with a battery-backed air pump for full outage coverage across both flow and oxygenation.
