Fluval Evo 13.5 return line upgrade

[HADA]

When you upgrade your pump and upgrade your nozzle line and using RFGs, can you use a 1/2 inch y and lines to get better flow? Or is it to much? I know the 1/2 to 1/4 line restricts the flow some. Thanks

IME usually it’s best to use the plumbing that your pump recommends. What size plumbing does your new pump suggest?

I am talking about the return nozzle.
