Back to the original question, and knowing that I already have the clarifier in hand from when I was pool stored, is there any adverse effect to using it if I don't overdose? Is there any reason not to use it for the purposes I described? Will it throw my perfect chemistry into whack if I use it to help with the particulate matter I can see in my pool at night?

Or, will it work as advertised and help clear my water up a bit?

Keep in mind, my pool looks crystal clear during sunlight hours. I've never seen water look so nice and pretty. I owe it all to the BBB method and stuff that I have learned on this forum.

I'd just like to look at my water at night with the pool light, and stare in total and complete awe at it's utter perfect clarity. I'll add some DE this week, but I was thinking about using some clarifier this evening if there are no otherwise adverse effects.
