Amount to bet to drive opponents away?

[Str8Fish]

I was sitting at a table with AQo first position... I call and so do 5 others [6 bets]. Flop is AcQs5c giving me a decent set of 2 pair. Now I'm thinkin to myself... maybe one of these people has 2 clubs and may be going for his flush... so I put in 8 bets more figuring the next person who calls would have to call 8 bets out of 14, or 57% pot odds. This SHOULD clearly drive out someone going for their flush at 35% hand odds, assuming they didn't pair. So question... was this too aggressive? Should I have chanced putting a bet down that gave them a better opportunity to see their flush? Obviously I'm not giving you all the details about every player, just answer in general terms.
