thanks for the recomendations

Another question pertaining to my setup. . .
planning on going w/ cpr Bak Pak 2/R, lots of live rock, and was reading a book that encouraged not to use a sand medium b/c it collects nitrates in a berlin type setup(unless a plenum utilized). Does this mean I should not use the live sand (that I already have)?, or does it refer to non-live sand?Or, will I just have to make more frequent water changes?

(I can't do a plenum because it would take up 1/3 or more of total area in my tank, and greatly restrict view)

And, is it possible to have too much light over the tank? 2--175w bulbs, obviously, would give me 350w(8+ watts per gallon), + whatever wattage of the actinics.

I appreciate all you guyses' Help!
