Thanks brandon, when I started the pico tank I took everything from a very well, established tank (a 330 gallon tank!). Maybe that's why I have so much coralline (I did have to scrub the acrylic once 8O ). There was only a slight cycle, but everything seems great! I did have one problem with it when I went away for four days and my pink cloves died.
I was thinking of getting a lid (topoff system too expensive for me, plus I have no room in this one bedroom apartment I share with my BF, cat, rabbit and guinea pig, not to mention two small tanks). I don't mind topping off both tanks everyday.
The 10 gallon does have a lid that protects the light, but because I've decided to put my skimmer behind the aquaclear I don't have lids on the filter or skimmer.
Right now, I do water changes using conditioned tap water and instant ocean salt once a week with the 10 gallon. The pico gets water changes twice a week using water in the 10 gallon. I top off both tanks with bottled water only because I'm too lazy to store conditoned water.
I think that's it, did I miss anything? Anyway, thanks for all the comments and stuff. 8)
