Lunar lights

[Yellow Eye Tang]

Just a quick question about using the lunar light. I have a 20g freshwater planted tank and I was wondering if the lunar light causes any problems with the overall tank. Can it create algae or cause harm to the plants?

No, they won't do any harm. I've run them on my FW tanks with no issues.
