good morning, i have been reading here about people being able to see copepods in their tank, what is the trick to seeing them and is there a certain color of light that makes it easier to see them. also i have read about copepods, tigerpods and others. what is the difference btwn them. my local store has bottles of orange pods and those that talk about copepods say thiers are white. ( just one of those things that make you say hmmmm) THANKS
