q about the actinic (blue) bulbs?

Hi,

I was wondering if those blue bulbs (actinic) have any effect
whatsoever on the plants even though they have high wattage?

Does it have the same effect as the "white" lamps?

They're only for marine tanks.

Thx, so they do not afffect the plants whatsoever... interesting.

Freshwater plants will use the blue light, and I've had actinics on a
planted tank in the past (it was converted from a reef tank) with no
ill effects. But it provides no benefit and the plants actually receive
a little less usable light/wt than if you used a more balanced lamp.

Thx, I was thinking actually of getting one of those dual bulbs systems
and use the blue bulb to simulate dawn/dusk effect on the tank and the
10k daylight and have leds for the moonlights.

Am I crazy with this idea in a freshwater planted tank?

I'd get the dual system but use 6700K bulbs instead. You can always add
the moonlights if you want.

Sounds beautiful and I don't think it would harm anything. I wonder if
there's something rosy or orange you could use that would look even more
like dawn? Maybe a normal fluorescent with one of those silly color
sleeves you can sometimes find at aquarium shops.

Yeah, fraid so. Lots folks try this and discover as the books say it's
light outside of the range plants can use. You might like the looks
but it does the plants zero good whatsoever.
