q about the actinic (blue) bulbs?

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.

Maybe an incadesent light on a dimmer. Need some way to increase the
light automatically over time. That would be kinda cool.

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.

I will have to look for it later this evening but I seen a site that had a
DIY guide to making your own moon lighting set up.

I bought one of the Aqualights you speak of.
The night effects are nice. However, I was informed, by a sales staff
member, that Bacterial algae may become more prevailent over time. Don't
know for sure my self. I've changed the actinic bulb out for a plant bulb.

Desalination plant will use a blue light, I have a actinics plants in the past cylinder (which is converted from a reef tank), no adverse effects. But it did not provide the benefits and the actual plants received less available light / weight than if you use a more balanced light.
