Turned full house, check or bet? ($25NL)

Sorry for a basic question. Is it better to check or bet the turn when I fill up? Opp is 28/12/0.75.

Great spot to bet b/c he might have made his flush and if he has trip aces, he's still probably calling. I make it $1.50 on the flop and $3.50 on the turn though.
