Unfortunately I sold my Tunze (too powerful for 3' long tanks). I have Seio 1500s, but I think I would plug in my 4.5w Hagen Maxima air pumps for the fw & the Seios (26w) or Maxijets (20w) on the sw. I also have another spare Maxima so if it looks like a long outage, I'll plug that in instead for circulation. Our central heating system is natural gas so hopefully that will still work & I won't need to worry about temperature.
My Motomaster Eliminator is the 300 amp version, not the 1200 amp like Chad's. I think for you guys (Chin & TomR), the 1200 amp version would be best, but I got mine on special (1/2 price) so that's why I went with the 300 amp one. I also had another small battery pack & I will be picking up the battery operated air pumps for back up to my back up
Chin, if you want to test it out on your Tunze, you're welcome to borrow it.
