Setting up fish room system - help

[Fat Puppy]

Giday all,

I'm finally going to set my tanks (35) up in a complete sump(s) system.  I have done some searching and most articles are based around setting up 1 or 2 tanks.  I have about 35 atm and I would appreciate some info if anyone can point me in the right direction into setting up a complete fish room with multiple sumps and plumbing.

I have been through quite a few fish rooms and asked question etc but is there somewhere I can get more DIY info on full blown system setups?

I have been looking at drilled verses overflow systems and still don't know which is better, also any info on battery backups for the systems would be much appreciated.

cheers Mike
