Hey, I just realized, this is a $3 project. Worth the up grade. 6 24 oz Coke bottles ( free ), 5 Air line T's ( $3 ), Glue - aqarium silicone is what should be used, but I have some epoxy that should do the trick for $5 less. Line ( have some extra ), and thats all folks. I will get too doing this soon. Soon as I have the bottles, and by that time I will have the T's bought too.
