I think the light timing between your fuge vs. the lighting of the main. Most folks (depending on the macro algae) will run their fuge lights 24x7 and the tank lights will be on their separate lighting schedule. Remember pH fluctuates, being lower after lights off and higher after lights on.

There may be a difference between a true fuge and the main, but not between the sump and the main. A true fuge has slow water movement through it. The lighting of the fuge on an opposite main tank schedule is supposed to even out the pH swings. Lighting it 24/7 will have no effect. When the main lights are on the pH will rise and when they are off it will fall.

However, I do have my pH probe in the main, hidden behind the rock.

Well, got the rock in this AM, had to pick it up at the airport. The box was a bit heavy having 140lbs in it (I ordered 130). This gives me about 150lbs in the display, and the other 3 in rubble in the fuge..



Still a slight haze to the water from all the stirring. I moved the sand forward and placed the rock directly on the glass, then moved the sand back. I think I'll need another powerhead or 2..
