I need an affordable uninterruptible power supply (UPS) for my 55 gal tank, giving me 1 to 2 hours of up time.

I prefer the American Power Conversion (APC) brand, but they advised against any of their models that output a stepping sine wave since this could damage the filters. Cyber Power has given me similar info.

The problem is, APC’s models that output a pure sine wave are WAY too expensive.

Are there any UPS manufacturers out there that make aquarium-compatible UPS’s?

FYI:

The APC model I wanted to buy: BE750BB for $99.99
The model APC recommended: SUA750 for $309.99
