Glued Sand Bottoms?

Cool thanks,i just wanted to know if your using full BB methology.I forgot your zeo aswell,and one other thing that has interested me lately is most ppl using BB method have had to dramaticly lower their photoperiods.Most are down to 4-6 hours a day with MH and a 3 hour dawn dusk.This might be due to ozone clearing the water and too much light penetration.

What photoperiod do you run your halides? sorry for all the annoying questions.
