Zandor - I drilled 8 holes in the bottom of the trash can....each hole is the size of a fat pinky. I modeled it after my previous 1 gallon pot that already had the holes predrilled.

JDogg - You might just be right. I thought that the yellowing meant that it needed nitrogen, so i've been giving it a dose of bat guano every other time to try and rectify the problem. Now i'm just giving it fresh water and superthrive. I have a PH pen coming this week to tell me EXACTLY what my ph in the water is.

Thanks for all the help.
