Lighting Minimum

[IceTurf]

Well I've found a way to keep the evaporation levels in check, a simple auto top off system, and for a smaller tank I don't have to be worried that the auto top off will run dry of a day's worth of evaporation. Yea I know, bigger is always better, unless you have no place to put the bigger. I may just give up on SPS corals for a while.

If you had say a tank, that was completely closed, with no area or space for evaportation and for outside influence, but with clear sections to allow for light to get in, could SPS corals do better or worse in an already cycled, closed tank? *assuming that you could somehow add calcium and other good stuff to aid it with life functions*
