what would be the best tunze setup on a 30" cube

what streme pumps controller etc?

2 tunze 6105 on multi controller either 7095 or 7096 will be your best option. That will take care of all the flow and avoid the future upgrade. Remember you can always dial the pump down if you have too much flow but you can't increase the flow when you already have it max out...
