15 gal lights?

[Chris333]

Just starting up a new 15 gal tank. I have a left over (salt water) Current light that holds 4 24W t5 bulbs. 2 are antic and will need to go.

Question is the other 2 bulbs are 2 24W 10K bulbs. Will this be enough for a tank with pressurized CO2. I would only be running the 2 bulbs, but have room for 2 more. If I need more what K bulbs should I put there?

Edit, My lighting fixture specs:

Nova Extreme T5 Ho Light Fixture - 4 24 Watt Lamps : Powerful, yet space-saving High Output T5 lamps make the Nova Extreme fixture the ultimate lighting source for reef aquariums. Featuring all the light your corals and other reef organisms need to thrive: 460 nm actinic blue lamps and 10,000K ultra daylight lamps. Each lighting source runs on independent circuits so you can customize your day/night cycles

Thanks
Chris

it will give a rough idea how much light you will have. I'm not an expert but i'd guess you have pretty high light with just the two bulbs.

I like bulbs in the 5000-1000K range, but prefer 6500 or 6700K

Thanks for that. Perhaps I'll change one of the 10K bulbs for a 6-7K.
