decided to drop the 10 idea, and bought a fixture for my 40g for SPS. thanks
Probably a good idea. The 10 can be a sump for the 40 if you dont have one.

Does the ocean get water changes?? Just top-offs, correct?
I mean.. think of what a hurricane does to the ocean.. brings up debris, breaks/kills coral, fish, inverts, etc.. the ocean is massive enough to take care of the ammonia spikes, etc..
but in a 10 gallon tank.. going from steady parameters to a water change with sudden changes of nitrates, possible small ammonia spikes, etc., could be harmful?
Actually, I think of it that the ocean gets perpetual water changes. It has an infinite deep sand bed and very high flow conditions with pristine parameters. Fresh ocean water is constantly being brought in to the reefs from the open ocean which replaces nutrients used by the reef critters.
Daily events such as evaporation or top-off (rain) have unmeasurable effects on the ocean because of the scale of it compared to the scales of our tanks.
when you have a smaller tank, the natural cycles (evap/top-off, nitrogen, calcification, etc.) have greater effects the smaller the scale.
Water changes are supposed to match the parameters of the tank so that there isnt a shock when you perform one. Also, on the 10g, you wouldnt want to do much more than a 10% to 33% water change at a time.
But Howard, if youre having succes with your 10g, then you must be doing something right. So you wont need to change what your doing.
