Light Settings

[PranavNath]

Hello guys, I am new to this group. I have a nano marine tank. There is some marine algae. The light I use is the Spectra Aqua knight v2. My doubt is, should I use blue light or daylight setup in this tank? Blue or daylight?

Its really up to your personal preference. There are long and heated debates on here about how the spectrum impacts growth rates for corals, but with your livestock I think its mostly a question of aesthetics. Some people love the neon look of coral under blue light. Others prefer the natural look of daylight. Try both and pick whichever you like would be my suggestion.

Welcome to the reef!

The “white” light contributes more to algae growth.
But personal choice.

Thank you sir,
it's seems to be covered brown algae over the algae, under the white light.

But brown algae appeared to decline under blue light.,

Yes, but there are other ways to combat algae if you prefer the daylight. If the tank is new, some algae is inevitable and just part of a maturing tank. Snails can help a lot.

Yes, sir, you are right, this tank has been built less than a month. So I'm going to have problems like brown algae right? Do snails eat live algae?

Yes, absolutely. They call it “the ugly stage” and it is something every new tank goes through. Just be patient and as your tank ages it will become less of a problem as long as you keep up with water changes. Good bacteria and coralline algae will outcompete the ugly stuff eventually. And yes, I think snails are an essential part of a clean-up crew in any tank. They will eat the algae and any leftover food waste, keeping your tank clean. I suggest trochus or astrea snails for the rocks and nassarius snails and conch to keep the sand bed stirred and clean. Since your tank is pretty new, you may need to add them slowly to avoid overloading the biofilter.
