The reason I bought the fan was because the first two days I had my MH set up my tank got to like 84 degrees. Since I set up the fan to blow on the bulb it only gets to 78.

As Bang Guy already explained single ended bulbs already have UV protection. I'm not sure why water would splash up 8" or so but if it did there's a possibility it could shatter. I personally ran 2-400w MHs for over three years with no protection and never had one break... even the time I was cleaning my powerhead and accidental sprayed one :scared:

Tell you what. I am diving with Eric Borneman on Thursday. I am picking him up and will be with him for 3 days. I will ask him, I bet he says otherwise. But I will post what he says.

Once again..you guys live dangerously. Come on. What do you mean how can water splash 8" ?? You have a tank for 3 years? This is a difficult forum for me.

I deleted that part. Who I am to say that I think you need glass protection over your tank from exploding bulbs by some happenstance. If you don't want to, don't do it. I would never offer that to someone starting this hobby. If others wish to, fine.
I personally think that is poor advice, but that's me. That's why I changed it. Seems if you offer an opinion- there is someone right behind saying BS. "i have done that for years" Well that doesn't make it right and you just got lucky.

I did not say I had a tank for three years... I said I ran 2-400w MHs for over three years. There is more than one way to run a reef... if you want a shield then fine but I don't see where they are nessesary when running SE bulbs. If you think that is poor advise then we can agree to disagree. A lot of people run MHs without protective shields and do not have any problems... not just me.
Living dangerously... a little off the deep end I'd say.
