do these look happy/healthy?

Do these happy, i just started running 2 1150 powerheads, theres white lines on them not sure if that's color loss or what, but i couldn't tell ya if thats how they looked before, as i never payed close attention because i didn't know that they were polys on my live rock when i bought, but im not an expert but i think they look ok to me?
