If it does, then Im reconsidering running my fuge light the opposite my tank.
That's the way most do it, but I found it to have little effect on the swing. I found that dosing kalk when the lights are off keeps things more stable.Seth The Wine Guy;724870 wrote: If it does, then Im reconsidering running my fuge light the opposite my tank.

But nowhere close to our tank swings - just consider the billions of gallons that are unaffected by light changes and that in our tank almost all water is "lit"...

Even though the water is shallow at these points there is still water transfer by passing water from high and low tides. For example if there is 10 feet of beach at low tide and 3 feet of beach at high there is 7 feet of water plus depth plus length that gets replaced approximately every 12 hours or so. So you take that volume and pull it into deeper water churn it up and mix it with deeper water and then you bring that same volume back in with all new nutrients. Even though the water depth at reefs does not change, the water volume passing by on these events does replace the water. So effectively there is a water change performed every 12 hours or so at these reefs.

Example: Fill the bath tub with water. Take an empty five gallon bucket and push it down in the water right side up. What happens? Water level goes up. That action won't be an effective one for an exchange of water from different depths to take place. It just causes all existing water to rise.
