Inexpensive nano lighting

[targa81]

The LOA quad is 6500k. I'm considering adding it to my nano but I'm wondering if it will look too yellow.Since I would be adding to one 10000k PC I'm thinking the combo would be ok. BTW I've read that coral growth is best at this spectrum,that is 6500k.So are the LOA lights yellow from anyone using them?

I was under the impression that the proper spectrum was around the 6k region, the colour temp closest to the sun? And that we only use higher K bulbs because they are more visuallly appealing, but dont offer the same amount of growth as 6k bulbs?

Different wavelenths of light penetrate the water more/better. So as you go deeper, only certain wavelengths are present, or in high concentrations. So corals are not exposed to 6K sunlight, they get "filtered" light, with higher concentrations of blue light because it penetrates the water better.

So higher K lamps are used for coral growth, and visual appeal. Different corals, depending on where in the reef they are, will "want" different spectrums of light. They can also adapt though, and change out the symbiotic *cant remember name* and get food from different spectrums of light.

That is a pretty good impression. Sunlight at noon at the equator is 6400K, so I believe daylight bulbs are around 6500K.

It is Red Sea wave tank. Kind of cute, but only 2.5 gallons. It probably won't be set up for very long. That is why I only used inexpensive lights.

Yes, that is why they call them daylight bulbs, but this is not necessarily the "proper" spectrum for corals and fish because they are underwater, not on the surface of the planet at the equator.

nice light might try to get one for my nano good score Bob nice and cheap

[Skimmerking]

ya that would work on some ones nano to light a AC 500 for a refugium.

Almost exactly what i need as well!Nice one BOB :>
