Want to get the best color out of your colors? While most people look toward blasting their corals with blue lighting, this method is only temporary and isn’t guaranteed to work. Instead, pristine water quality is the best method for maintaining coral color. Keep the nitrate and phosphate concentrations low, and we guarantee your corals will look their best. Sure, blue lighting won’t hurt, but having a good handle on nutrient export and control will yield long lasting results that will also translate into healthier corals.
