thank you for the input, much appreciated .. although the "no water change" suggestion kind of surprises me. everything i've read so far has suggested daily siphoning of any visible offenders. what is the benefit of waiting out the 3 day "lights out" period before removing them?

my RODI water tests at 0 for TDS .. what do you find as your correlation between the two, Miz?
