I'm planning to dip my toe to saltwater. I have 25 litre aquarium that I want to turn into pico saltwater tank, and one thing that baffles me is light. I'm thinking of getting liver rock, and perhaps some macro algae (that's not invasive, like Cladophora prolifera or similar) and shrimp or two. Usually light recommendations seem to be mainly blue, but should I get something like Kessil A80 or use my current, (really bright) white light? Sorry for possibly stupid question, I'm trying to avoid mistakes by learning as much as possible before actually setting up the tank.
