Ahh, OK, perfect. Great advice, Brian - thanks!

I will look into the dracaenas/corn plant. And I will keep that in mind about the perlite, too.

I have not done a water test - I used tap water treated with dechlorinator, same as I have used for the last 6 weeks or so in my little 10 gallon (Hope's current residence). What constitutes a water test, and what do I need to do it?
