Suggestions?

1. Use the 10ml sample, with 1 drop equal 0.5 ppm chlorine, instead of the 25 ml sample. With the chlorine levels you need, using the 10 ml sample will save a lot of FAS drops!

2. Read the "Best Guess" page, linked in the blue signature block. It will explain recommended chlorine levels -- and why you need to follow those.

3. Can you take pictures?

I've ordered a Pentax Optio WG-2 precisely because it is supposed to do very good macro, with some dedicated LED ring lights . . . but I don't have it yet.
