Question from a Sump Newbie

[Cap'n]

Why 1" out and 3/4" return? Is there a reason for the different sizes? Easier to pump the return line through a smaller hose I would imagine, is there anything else?

I don't have predrilled anything, don't plan to go that far yet.

So I don't even need the extra powerhead in the overflow, I just use gravity and put the powerhead in the sump for the return line, it keeps getting easier! Now, if I wanted to put the two tanks beside each other I would have to go with something more like my original description.

I guess because I was never really using the info I was reading about plumbing I just skimmed over it.
