[King Triton]

Found! thanks so much for all the help!
Im looking for external pump or sump pump, high gph flow...
I am running 2 15,000k and would like more color so a 10,000k would be nice even if someone hears of them on sale. thanks!

You will get less color with a lower Kelvin bulb. You would be looking for a higher Kelvin bulb. I have a couple of Coralife 10,000K bulbs and I use them for backups they are horrible bulbs with really bad color. Looks like someone peed in the water! :eek:

Ya 10,000k is more for growth but also more yellow.
You will want to go to 20,000k then they will be more on the blue side.

Lol same here I have a 10,000 running over the roonates tank and it kills me to turn it on no color out of anything , I run a 20000 on my zoa tank but since it's the only light I wanted a blue color. I get growth on the slower side but yet all my corals are bright and stand out. I'm gonna try out the 14k for my new set up to get the best of both worlds :):)

Thanks for reply! I had 2 20,000k and found they do not last long. Between the actinic lighting, 1 -14,000k and a 10,000k it seems to give a blue spectrum yet still yellows in it with good response from corals.

i could be wrong but its my understanding that a 20000k bulb should last longer but they all should be replaced once a year:):)

I agree, I just didn't have any luck. Never held the bulb. Just no luck. Perhaps they got to hot. Fans are working. Vacumed all dust out, clean glass. All I can think of. 3- 20,000 less than 6months. at 150.00 a pop.
So stick with what works I guess. The 15,000k are good so far.
Thanks.

When you say "never held the bulb", do you mean the color faded? The bulb fell out? The bulb broke? What exactly happened? The color will fade in all bulbs more towards white/yellow, but many people run higher Kelvin and run their bulbs longer. Start bluer and it will take longer for them to fade to an ugly color. However, all halides should be replaced yearly to keep the PAR at a decent level.

You're using the Coralife bulbs each time? You're paying $150 for each Coralife bulb?? I would suggest you change bulbs. Coralife is not the best brand by far, and if you're paying $150 for each bulb that's ridiculous! I would suggest you switch to the Phoenix 14,000K bulbs. Should run you about $65-85 depending where you get them, and they are a great bulb. The quality of them is much greater than Coralife, and the color will be outstanding in comparison. You can't go wrong with the Phoenix bulb.

Keep in mind that what the manufacturer lists a bulb at can be very different than what you actually see when you turn it on. Also, different ballasts will fire the same bulb a little bit different so there will be color variances there as well.

Seeing as you're in Didsbury (Ontario I assume), maybe try ordering online from a company that offers free shipping over $100. Although I rarely recommend them because I prefer to shop locally, J&L Aquatics in BC carries the Phoenix DE (double ended) bulb, and they offer free shipping over $100. Two of those bulbs shipped to your door via UPS from J&L will cost you about the same as ONE of those Coralife bulbs you're currently buying! They list the 150w at $53 ea and the 250w at $66 ea.
