Considering this UPS
http://www.circuitcity.com/ssm/APC-UPS-Surge-Protector-BE550R/sem/rpsm/oid/177693/catOid/-13011/rpem/ccd/productDetail.do
• 550VA/330W output
• 65 minutes of backup
• Eight outlets
• Battery alarms
id use it to run my koralia, and a MJ 400 probably, how long do you think it could run these for? total watts by the pumps are 17 watts
thanks
You might be able to get an hour if you are lucky. This UPS is a higher priced, http://www.newegg.com/Product/Product.aspx?Item=N82E16842102048 should be able to give maybe 3+ hours.
Hi Mike,
First I'm positive you can get that unit for much less -- check pricegrabber or eBay for starters. The unit ZrC mentioned is a little better. NewEgg is an excellent a good retailer, also check ZipZoomFly.
You may want to read this (http://archive.reefcentral.com/forums/showthread.php?s=&threadid=1223212) recent thread on RC regarding UPS devices and generators for power losses. The question I have is why you need it. Most tanks will be fine for a few hours during a power loss, with the first concern being O2 issues -- in which case you can spend a fraction of what you're looking to spend for one of these (http://www.championlighting.com/product.php?productid=27601&cat=421&page=1).

That APC UPS might not reliably run your Koralia. I had a Koralia plugged into a bigger model from APC and it worked fine when I first plugged it in and tested it. When the power went out you could see the Koralia trying to start but wouldn't quite turn over. I contacted APC and they told me those models were designed to back up electronic equipment, not motors. They said I needed a UPS that output true sine wave or something like that. For that APC line, that would be the SmartUPS 750 and above. I found a remanufactured SmartUPS 1000 from a link someone posted here and that one runs the power heads.
