No sweat, I will just say take ur time, read/research, and ask heaps of question. Also just incase you have been lead astray, careful who you get advise from (not to say I'm any better ;)) . I noticed from your pics and from your post you have just setup a nano as of Tuesday and you already have Nitrate, KH, Phosphate test kits along with Trace Elements, Cal, Alk. Now there is nothing wrong with having these items already and I'm not sure if this is the case or not and dont want to accuse anyone of anything, but I wouldn't thing that you need KH and Phosphate test kits along with Trace Elements, Cal, Alk for quite a while yet......... Wouldn't want a LFS taking advantage of a newbie.
Thoughts anyone????
