sump size for a 75g

Hello
What size sump should I get for my 75g. My 75g is 3ft long. I'm able to fit a 10g tank through the door. Also, what is the best HOB overflow? So 1" ft long 1" high.

 

I have a 30 gal. sump on my 70 gallon tank.

 

I would go with the largest sump you can fit. a 20 long should be alright. You may have to turn it in order to get it through the door. Will the refugium be separate? Like AM said, you could go with a 30g as well.

 

10 gallon would work but more is better for more stability. Whatever the largest you could get in there would be best. Post a pic with the door(s) open so we can give you better suggestions. If you can remove a brace you could get a larger sump in. If you can squeeze a 20 in there that would be great.

 

If you put it in the door at an angle then turn it(once in the stand) I think you could fit a 20g Long under the DT.

 

Ok, I got a 20g cracked to test that. What is the best hob overflow?

 

Go with the Eshopps.
