Ai prime on 40 breeder

[sharkreef]

Hey wondering if 1 ai prime would be enough for a 40 breeder

Not in my opinion. Two would be minimum and three if you're doing it right. I have a 24" tank and briefly considered two of these. I'd say one per foot to eliminate shadowing and dark spots as much as possible.
