For those of you who only change your bulbs every couple of years, how has your growth and colours changed? I'll bet that for most of you the bulb spectrum has faded do much that your corals are not as bright and that your growth rates have slowed drastically. I figure my 60 gallon is worth about $5000 equip and livestock. What is it to spend $100 on new bulbs every year? That is only about 2% of your investment in maintainence, very minimal considering the maintainence costs of other expensive things like cars and homes.
