Someone offered to sell me a 1400VA UPS. I was wondering if this was good to use as a backup power source for the reef tank, probably just powerheads and How long 1400VA would last for a 8-10watt powerhead?
I read a thread on RC sayng that you couldn't. It has to do with the wave form? that the UPS generates. I will try and dig up the thread. I don't know how much a small powerhead would be effected versus a larger pump.
