I want to resurrect this thread because I'm wondering the same thing. I'm putting together a 75 gal that'll be mostly lps and fish. I have ai sols (that have a controller) and plan on adding a bml strip to fill in the missing colors. Besides that, a couple power heads, ato, refugium light, return pump, skimmer, maybe the wavebox I have, and that's all I can think of right now. I don't run heaters and don't anticipate a chiller with the leds. My tiny nanos stay just the right temp without heaters/chillers, so I'm assuming this much bigger tank won't need them either (right?). Not planning on any fancy reactors, but probably one with gfo and/or carbon.
As for the power heads, I'm almost sure I'm going to get 2 controllable tunze ones. So I need to decide to get the tunze controller or spend a little more and get an apex or similar.
So with that list of equipment, what's your opinion? I really don't know anything about them except what I've read in this thread. Mostly I find them very very confusing. I like to keep things simple but I'm doing my best to set this tank up right from the start rather than upgrade down the road and waste all that money replacing stuff.
Thanks!
