well, we have 2 wall units that we plug into..that are both protected by a plug in gfci unit. One has a power strip coralife timer plugged to it where all the lights are timed and power heads also on there and skimmer on the always on plugs. The other the backup battery is plugged into, no different than a strip but a very heavy bigger box. On the back of this we have plugged in our filter, one powerhead I think, the heater...that is it..so in an emergency we lose power..the other ones are off...that are plugged into the coralife timer....*it has 4 slots of timer, 4 regular plugs. When we lost power....the battry backup made a loud obnoxious beep through the house, scares the #$#% out of you. Then the filter and heater and the one powerhead never shut off. Once it got to the 2 1/2 hours, it beeped loud again as a warning that it was almost out of juice, that is when we switched to the other battery backup...and put the one out of juice on the small generator. Was fantastic....we could have done this indefinitely...was a good system and not too expensive. Battery backups we got at an auction for about 20 bucks a piece, new they are probably closer to 80 but try to find some on sale...I see them regularly at officemax and places like that. Let me know if I helped explain that ok!
