what do you keep your tank temps at?

[maxdout]

i currently have mine set at 78.5. i was running it at 77.3 for the last couple of months and notice that the corals weren't growing much. I decided to up the temps and noticed more polyp extension but at the same time green bubble algae started to appear. I used to have them and did a manual removal of them at the start of the cycle 9 months ago. It is getting to the point of me having to take it out again and remove them manually. i was thinking maybe it was becuase i upped my temps that they've grown out of control. anyone with info on tank temps and bubble algae removal tips is welcomed. thanks
