Quick question while tank is filling

[Ryanz27]

Ok.. maybe dumb question but.. I have a 75 gallon im starting up. I havent done a tank this big before. How high should I fill the tank up to? how far from the top?

inch bellow? if you have covers.

Doesn't really matter. I leave enough space that surface agitation is not interfered by the covers.

If you don't have cover or your fish likes to escape then I would go 2-3 inch down. But normally that is not needed.

My tanks have a plastic border around the top, around a half inch. I keep the water level just above the bottom of the border.

I fill my tanks a little above the bottom of the brace/rim/trim for most my tanks, unless a specific situation/fish calls for anything lower.
