Replacing bulbs

I have a Current 80 watt PC Fixture. Currently I'm running 1 - 6700k/10000k bulb, and 1 420/460 bulb. I have read actinics are more for show. When I replace my bulbs, would it be more benefical to run 2 6700k/10000K bulbs, and add a Current LED light strip with 4 blue LEDs. I'm trying to get more usable light for my corals, with my existing setup.

 

Hello, This can get a tad deep but all the basics are there and I think you will come away with a better understanding of lighting your aquarium.

hmm

Okay I read you article, and it was easy to follow. Is states 10k is preferable over 6700k, but actinic combination is needed. So here's my question. Should I go with the combination I have now, 2 bulbs that rate 6700k/10k with a Current Actinic 4 LED, or 2 bulbs rating at 10k/460

 

actinics really help corals grow. They produce the wavelength that corals need to grow and prosper. They also had to the visual appeal of the tank. I would not replace your two bulb set up with just two daylight bulbs. In saltwater, actinics are just as important as daylight bulbs.

 

Are you using combo bulbs?

 

Yeah My PC fixture takes sunpak bulbs. 2 Bulbs in one. The available choices are 6700/10000k, 460/420, 10000k/460. I can use 2 of these in my fixture.

 

I realize I need actinic, but 10k is pretty braod spectrum. That's why I'd supplement them with a LED strip.

if you use two 10k/460 you should be ok

 

That's what I was thinking.. I heard 6700k promotes algae growth.. why people use them in their fuge. Thanks for your suggestion! Is 420 spectrum useful at ALL?

 

I prefer the 10,000k/460 and I have added the Power brights also to get the shimmer and deeper penetration.
