getting closer, a few more questions

[Jarett]

what i have so far:
basically two tanks, one is the main tank(glass), and the other one is below it(acrylic). the one below is one i custom built that is a sump in the back and a tank in front. it was going to be a fuge. all this is built in to the wall, and from the front you can see just the front glass of both tanks. top tank i want to keep sps, and the bottom tank my wife has claimed as hers.the bottom tank will have a 7"sand bed, was planning on the samefor the top, but im concerned about all the flow the top tank will have(closed loop with a dart/oceanmotions),
can i go bare bottom, or maybe just a 1" sandbed on the top tank? will the bottom tank be enough with the dsb to control both tanks?
top tank is 36"L x 18"W x 24" tall
bottom tank is 28" x 10"w x 24" tall

thanks, pleese give any input because i want to put the sand in soon, rinsing it all as we speak

You can do as you feel there are no set ways of doing things

If you have lots and lots of flow a DSB in the display will become messy unless you find a way to dirrect water without disturbing the sand bed. ........Same with a shallow one ...........
