Triple barrell bluff readless

Hi,

What is your opinion about triple barrelling readless.

I was strongly considering doing so in the following hand, but I stopped myself. Given the low stakes I'm playing, I'm noticed many opponents are very loose and are likely to call very often. However, in general would this be a good spot to triple barrell?

Hero (BTN/SB): t1500 75 BBs
BB: t1500 75 BBs

Pre Flop: (t30) Hero is BTN/SB with 6 Q
Hero raises to t60, BB calls t40

Flop: (t120) 4 K 8 (2 players)
BB checks, Hero bets t80, BB calls t80

Turn: (t280) J (2 players)
BB checks, Hero bets t120, BB calls t120

River: (t520) J (2 players)
BB checks, Hero checks

My thinking was that the flop was good to cbet (can represent a K, or a flush draw). Turn card allowed me to continue to play that image, hence my smaller bet (which I'm not sure was correct, perhaps half pot would have been better?). The river I feel would have been a great card to triple barrell on though. What would you recommend?

Thanks!!
