Drilling Tanks, Drain/Return Size? (1 Viewer)

[ITreefer]

I've acquired a couple more pairs of clowns to start this breeding thing in earnest.
I will be working on making a broodstock tank out of a 40 breeder this weekend.

The plan is to use 3 full dividers to split the tank into 4, 10 gallon sections.
Will be drilling drain/return holes in each section to plumb everything together neatly.

What size drain/return holes should I be aiming for? 3/4" & 1"?

Im thinking about using 4 of these for the drains, simply drilled into the back wall.


Does home depot or any LFS have the stuff I would need for this project?

Thanks for your help/advice.

On my 40 I have 3/4in return. And if you need a diamond drill bit I have one you can have, let me know and we can meet somewhere.

What size drain?
Thanks for the offer, I have the diamond bits on order though.
