Help ASAP!power head problem!

[Datreeferman]

I have a 30 gallon reef tank with 4 fish,soft corals and a candy cane coral. My power head mouth functioned and isn't working. I was wondering, how long can corals go without a power head? All I have is a hang-on-the-back filter for 25 gallons for back up. So how long can the corals last without a power head but a small filter? I have everything else working.
Thanks.

Just put the filter you have on there, as long as you have water flow of some kind they will be fine until you can get it fixed or replaced.
