UV burn from HQI lighting

[anadliv]

I have a coralife aqualt 150 watt hqi clamp on fixture. the bulb has a small glass shield that covers the bulb. from what i have read when using and hqi fixture you should have a covered aquarium to prevent UV burn on the corals. If anyone has any info please let me know if this is true or if uncovered tank is ok.

If I remember correctly the glass shields are the UV protection and are used on the DE bulbs. The SE bulbs I believe have the UV shielding built in.

Thanks for the reply, does anyone else have experience running uncovered tank with the double ended HQI
