My T5 bulbs are 3+ years old. Replaced only when burnt out.
Have 6xTek T5.
My tank has almost non existent algae.
My SPS have VERY nice color and growth I have Pink, bright green, blue tip Dual Color SPS and green tip as well.
So go figure.
Low bio load (only 3 fish in 65 gal tank ), high ORP (with high air flow) air driven skimmer it is constant just over 450. Second skimmer is Deltek 600 HOB.
