Attention plumbing guru's

[Pruett-nc]

I am setting up a 50 gallon low boy . The height from pump in sump to the top of the tank is about 4 feet give or take a few inches . I have installed a ghost overflow in the center back of the tank . I am using a sicce 5.0 pump .

I want to do dual over the rim returns if possible . I needs ideas and suggestions on size of pipe and fittings I could possibly use . The overflow pipes are 1" .

The tank measures 48 L 24 W 10 D .

3/4" returns

I looked up a calculator and said 3/4 uses more head than 1" . But I was thinking 3/4 also that's why I am asking guru's that have experience .
