Affordable Reef-Safe Aquarium UPS - Essential Power Protection for Marine Tanks
Get reliable backup power for your saltwater aquarium without breaking the budget. The CoralGuard Lite DC UPS delivers the same efficient backup power protection as our full system - maintaining critical water flow during power outages - but without the included charger to keep costs down.
Why CoralGuard Lite Beats Traditional Aquarium UPS Systems
Maximum Efficiency for Marine Tanks: Standard UPS systems waste precious power converting DC→AC→DC. CoralGuard Lite's direct DC-to-DC design eliminates conversion losses, giving your reef tank longer runtime and superior efficiency.
Budget-Friendly Reef Protection: At just $40, get essential backup power protection for your marine aquarium. Perfect for aquarium keepers who already have a compatible charger or want to source their own charging solution.
Extended Reef Protection: Compatible with affordable scooter batteries for long-duration protection. A 20Ah battery can power a typical 24V aquarium gyre for approximately 20 hours during outages.

The Real Reef Emergency That Inspired CoralGuard:
A few months back, I was battling a stubborn phosphate problem in my reef tank - you know how frustrating those can be. I had my regular UPS running my essential equipment when we got hit with a power outage. The UPS worked fine, but it just didn't have enough capacity to keep everything running long enough.
When I finally got to check on the tank, I discovered my filefish had jumped out. Thankfully I was home and managed to get him back in safely, but it really hit me - what if I hadn't been there? All because my backup power couldn't sustain the system when my reef needed it most. Not to mention, losing circulation during my phosphate treatment set my progress back significantly.
That near-disaster made me realize there had to be a better, more efficient solution for powering critical DC aquarium equipment during outages. Traditional UPS systems waste so much power converting DC to AC and back to DC again. CoralGuard Lite was born from this real need - providing the same efficient, long-lasting backup power as our full system, but at a lower price point for budget-conscious reef keepers.
