[JUBE-JUBE]

Hi,

I've been running my 6 gal nano cube for almost two months now and there's a buzzing thats started whenever I turn on my day lights. I have 18W 50/50 Power compact bulb that I run an avg of 6 hrs a day. Led moonlights as well at night but have no problems with those. I'm absolutely clueless when it comes to electrical (pumps, filters, water chem no problem but lighting...all those wires are boggling my mind) there doesn't seem to be any problems with the connections and I have to fans that run when the temp rises. There is some blckening where the two bubls meet. Any sugestions as to whats happening would be great and should I try replacing the bulb first before trying anything else??
