As long as all same height you be good. If controller to high then buckets flood and if to low then controller floods. You said spare bedroom, is rez and controller in same room as buckets?? I ask because you dont really want to "warm" your rez water and if in same room, unless air conditioned, the rez will heat up and depending how warm it might cause issues.

The nuter I would use are "Cutting Edge Solutions": Micro Rating: 5
