Which PC blues

[ron thomas]

Hi,
My 55-gal has a 4X65 watt JBJ PC over it. I have been running two 10,000k daylights and two 6,700K JBJ blue bulbs. JBJ now offers a true actinic 03 bulb. Since I am ready to change out the bulbs, I am wondering whether I should move over to the JBJ true actinc 03 lamps? What are the benefits and disadvantages of doing this? Also, can I buy the Coralife 65watt straight pin bulbs or do I have to stick with JBJ's bulbs?
When I replace one pair of bulbs after six months of use, it is awesome to see how much brighter the output is compared to the pair that has not yet been replaced!
Thanks for the input.

You can use the coralife bulb. They don’t have to be the same brand as the unit.
I use coralife bulbs and love them. I use all 10000k/actinic 03 50/50 bulbs. and one actinic 03 so that I can have a proper light cycle. dawn,day,dusk.night
personally I love the coralife color I get. Very crisp no yellow effect at all.
50/50 bulbs help you spread out the color a bit better but you lose the ability to have only actinic for your dusk/night effect.
