You can go with actual battery back ups for a computer and have one dedicated to pumps and powerheads. Or you could get battery operated air pumps that kick on when the power goes off and runs for like 2 days.

i have a computer battery back for my pumps. depending on what pumps you have and the size of your tank you might not need to use all of them in a power failure. in this case less is more, less pumps the longer they can run.

I bought one today at Staples for 150 bucks with LCD readout but it wasn't APC.

I would go with the APC but I didn't have the room for their big back up.

Well you need to look at which pump you got and look and see how much amperage it draws.Then you can figure out from there which UPS you need by how long you want it to run. If it was me I would just buy the biggest one they have within reason.

MC Assault for real? Crazy to see your name around here.

You need to get yourself a HUGE tank and spell out BIG OOMP in live rock!

I honestly would tell you to get some battery powered airpumps. I'll dig up the post but they say that they last 4 days off 2 D sized batteries. They are about 15-20 bucks each. I doubt that you will need that much time on them. You would need 1 for about every 2 feet. They will provide flow through your tank.

Here is a quote from me in a previous post:

Quote:
No battery solution is worry free. Eventually all battery backups must have the battery replaced. Some require changes yearly others every 2-3 years. Few make it five. Also, I am suprised you get that long of a run time. Converting DC to AC is actually very taxing on a battery system. You lose somewhere around 70% of the power of the backup due to this conversion. Most affordable battery systems are designed to run a light load under one hour. As the battery ages it also loses charging capacity. What it did when you first got it, probably won't be even close a few months later.
There are several comments and replies to the above statement with a good discussion of digital versus analog UPS systems, but the take away should be that most computer based UPSes aren't going to protect you for an extended period (day or longer in most cases). Frewl pointed to the thread that contains the full discussion above.

In my case the battery backup was bought primarily to run the return pump with circulation secondary however, I only have 8 fish and no corals.

The goal I guess is to protect investment and while most of yalls is big money in livestock, mine is big money in hardwoods.

I use a battery backup for 2 reasons:
1) those short power outages don't effect my system at all
2) it buys me time (especially if I'm not at home) to get my generator hooked up.
I only have my mag 9.5 & 2 Tunze 6000 w/ 7095 hooked up to the APC smart 750. That should "buy" me an hour maybe 2.

What happens when the power goes out right after you go to sleep or when you are away for a weekend? You could easily run for 10+ hours without anything going into the tank. It is an unlikely scenario, but it could happen.

If that were to happen, he would not be better off without the UPS.

I'm going with a 1500 apc with It's own battery backup, and 4 backup pumps. I get nightmares about power outtages. My two main tanks are being set up in a large converted barn with an outside closet housing a 400hp gas generator. my 135g and my 150g are in someones apartment. If any one comes up with a long term solution plz post.
