Can tank temps influence cyano?

[daddypugg]

I seem to be experienceing a cyano (more like a dusting) only on the sand. nothing to serious but enough for some concern.

I have a 110 with a 30g sump/fuge, I have some caluerpa and cheato in the fuge.

I have noticed that my tank temps have been rising lately, I caught it at almost 90! I put an extra fan on it tonight to help lower the temps.

My question is can the temp influence this dusting that I am having?

All my params seem ok (well to me) but here they are:

Trate: 0
Trite: 0
Amm: 0
Phos: 0.1
PH: 8.4
Alk: 3.31
Calc: 410

Thanks,
