I hve the 16 inch unit over a 30 breeder withh all z/p for 4 months now. Good growth and color. At the moment my highest setting is blues 28% and whites and burgundy 5%. Does anyone care to share their percentage with me and their light cycle? This is a frag tank and yes a like a smurf pee look lol when viewing my zoas. I just want to maximize my growth. Thanks for any help.
