Here's a good one.
Every day between around 2pm and midnight my Reef Angel controller shows a drop in pH from normal 8's to less than 6. I know it's not really dropping as my tank isn't dead and my Seneye doesn't register the drop. Reef Angel controllers will show a drop in pH with stray voltage in the tank, so I believe there may be some voltage coming from somewhere.
I have a fan blowing across the sump when the water temperature rises and the pH drop correlates with the fan being on. It isn't an instant drop, it is gradual and rises gradually after the fan goes off. It takes a few hours to get the the upper 5's where it levels out, and about the same time to rise to normal. I can reproduce the problem by turning the fan on and off manually. I do not get the drop with the fan on and NOT blowing across the water.
So what's going on? Fan causing a static buildup somehow? I put in a grounding probe (plugged into a power strip, problem?) with no effect.
Any thoughts or theories would be greatly appreciated.
