So here's what I've got.. I'm thinking maybe the meter is off.. Maybe not... Tell me what you think..
Ok.. The white line is showing from my tank.. The colored lines I'm guessing is your control. Because they don't move... My lux is reading 1000.. Looking that up its saying basically its an overcast day

What's your opinions?
