75g Pump Suggestion

I am in need of a new pump for 75g as my old one is wearing out. when i took it apart today i noticed wear on insiede where shaft of impeller sits. Can you recommend me something as to GPH 'cause sticker on old one is gone so not really sure what it was and how big it was.

Thanks

 

What's the overflow(s) rated at? Is the pump just returning or are you driving other things with it?

 

Not driving anything, i am not sure what is my overflow rated but it is 1 in. diameter with diy durso overflow

 

i use a blueline hd 40-x on my 75, pump sits about 4' below tank and return line has 2 ninety bends in it. flow seems to run at around 800 gph, and it's been quiet and reliable (running for 14 months now).

 

Now will i need a shut off valve to control the pressure?

 

i run a 900 gph on my 75 and does great sometimes wish had went with the 1000. I have a 2 in return and a 1 in feed.

 

so i should get as bog as i can afford?

 

maybe as big as system can handle 1 in return may not handle a 1000 gph pump. just check and then do what system can handle.

 

haha i found this calculator and it recommends for 1" pipe about 560-600GPH

 

there you go good luck now just pick from the types of pumps and you will be set. I use mag drive. worked for me so far
