Metaball and Duplicates

Hello all,

This is my first time posting and I am relatively naive when it comes to grasshopper, but when I create my metaball structure, it outputs a bunch of duplicates causing the script to run really slow.  How do I sort my data to make it run faster?  P.S.  I am very new to understanding anything scripting and algorithmic in terms of modeling since it is not something taught at my school, so clear and straightforward answers would be appreciated!
