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?
