Needed a spraybar to get rid of the dead spots in my planted tank. I've seen alot made of white PVC pipe but I really didn't like the color of it. If not hidden well, it looks ugly. I went shopping for materials and here's what I ended up with- all for as little as $5 The clear pipe is from Petsmart (this is 1/3 of the length) for $4.99. I think it's supposed to be for underground filters, so check the filter area for it. Suction caps also from Petsmart @$1.99 for the two. It's perfect because the black thing doesn't go around the whole pipe, making it look even better. A Poland Springs bottle cap fits the pipe perfectly- no need to glue it on. This allows for easier replacements (I have three of the clear pipes with different hole diameters). Just drill a hole through the cap like you did when you made your diy co2 bottle. And of course- the end cap, also a poland springs cap.
