return line help

[hockey00]

I have a 92 gallon corner tank with two 3/4" pvc return lines. I have a glass holes 1500 overflow box. My return pump is a quiet one 3000. I would like to get rid of one of the returns and go with just one. I already have three powerheads and the two returns, looks crowded. Will i reduce any flow from my pump? Any negatives with just one? thanks

One will be fine. Flow will be a little greater from the one return, since there will be no loss of pressure from splitting into two.
