Aqua One Mini Reef 120L Sump / Refugium - Week 5

An overview of my Aqua One Mini Reef 120L Sump and the new Caulerpa Prolifera (Macro Algae) that was added for reducing nutrient excess. Caulerpa needs a low Kelvin lighting rating. Mine are on 4000K and they usually require maximum 6500K 24/7, so they don't in sexual reproduction mode.
