Can you tell me what spectrum light's do you recomend for my dsb in my sump and the LR?

In general, pretty much the same as you would for the display. But it doesn't matter as much. As we all know, most algae that grows in/around our sand and rocks is not too picky about lighting...
Unless of course, you want to grow a particular kind of algae (like, macros or coralline)... in which case, here again, I'd just say use the same as you would for a display tank.
THANKS SIHAYA!! will do.
I would recommend about 4000K to 6500K, its quite yellow and simulated sun light, but the cheato will grow wild!
But No corel sun, reef sun or a ocean sun??
I would actually recommend this for a display tank too though... for the same reasons (is closest to natural sunlight). I like to use 6500K for both displays and refugiums. Since it is so "yellow," I also add an actinic strip in the front (just for aesthetics).
Sorry for this hi-jack, if only sihaya could just answer...... (to not take over this thead)
I've thought about this quite a bit, run the 6500K on the DT during hours when tank not view and change over to say 10000K when viewed? This would make the coral grow, but as well as the algae, which I've got quite a bit what is your take on this?
Primarily I dont recommend any light in the dsb as this is a biological filter and does not really require much light, the only time I would consider a light is when I want to grow something on top of the dsb. ( macroalgae etc. ) same for the LR compartment.
Sounds fine, I don't see any obvious reason why you couldn't do this. But you could also just run the 10000k all the time. I usually recommend 6500K because it's closest to natural sunlight, but I've used the 10000k too. The thing is that, ok... this could be a thread all by itself. 6500k bulbs (if actually producing what they are rated--which they often don't though), will produce less UV light (a factor in coral coloration)... but the corals might likely grow faster than with the 10000k.
Basically... if you don't care so much about your corals growing at record speeds, and if you care a lot about aesthetics, a 10000k bulb is usually just fine.
Am I making any sense here?
the rio mini sun, there is three colours, this is the day light, lcd lights
not sure what the kalvin rating is, anybody using this tipe of lights?
Hi Burt - unfortunately, have to give you some bad news. These Rio Sun LED lights won't ever be strong enough to help macro algae, ie. chaetomorpha grow.... sorry man..........
