Thats a great Idea, would never have thought of doing that! Nice one, Amy
That's cool, hope it's useful! Btw, instead of putting a stopper on the end, I heat it up and then snip the ends with a pair of scissors, it brings it into a V shape and seals it at the bottom, looks slightly better imo. I also drill slats into it with a small round blade, I personally thing it looks better than holes, although it does block quite easily.
Theres a good write-up over at Planted Tank forums about doing this
Awww, gutting - I was actually going to do a write-up! Oh well, I'll have to be quicker next time lol.
