I apologize in advance if this was covered in the past. What's the best way to have a workable ph probe around a power compact light (if there is one). I have two 96watt PC's about 12 inches above an open top tank, and the ph probe is in the water, I can only use the ph probe at night otherwise it's all wacky.
