Many Reef Jars been done before but I notice they have to do major clean up and algae scrubbing which is quite fast anyway so to keep the scrub cleaning to minimum and coral thriving is the right spectrum lighting.
I been done research with light spectrum and found a perfect light that incorporate the perfect spectrum that cover the UV 395nm, purple 420nm, royal blue 450nm and blue 460nm plus true 6500K that only utilizing 10W.
If you use more than 12W and wrong spectrum it will produce too much algae.
