AquaticLife Light Fixtures Owners

I have a question for any/all AquaticLife T5 fixture owners.

How Often Do You Change Your Bulbs?

 

once a year on a 6 bulb unit

 

Going to follow along. Just picked up an aquatic life t5/ hqi fixture.

 

same as any of my other t5 fixtures. every year.

 

I normally change mine out every nine months.

 

About once a year

 

I only ask because the offical website says up to 18 months

I have new bulbs in the mail, but my fixture I use now has had the same bulbs in it for over two years...and the only noticeable difference has been the lack of "blue" color coming through in my tank

 

Every 12 months for me.

 

Yup,the main reason for replacing them is that they lose their color spectrum and shift towards the warmer colors(yellow and red).When this happens they become better suited for algae growth and not so good for corals.
