Question about power...

[MikeP]

My entire system is running off of the 2 plugs behind the tank (a standard 2 plug wall outlet) and powerbars. I haven't had a problem but I'm wondering if I should try to find another plug to use so the demand isn't as high on the 2 I'm using now. My only option is a 2 plug outlet on another wall but I would have to run an extention cord. I also have a thought in the back of my mind about setting up a nano mantis tank plumbed into my existing system (yet more power used up from those plugs/powerbars). Am I pushing my luck or worrying for no reason? Clearly I don't know that much about electricty but would like to learn more.

Thanks!
