Thanks for the tutorial! You rock! Thanks to you I now plan to run all "hardline" in my desktop nano.
I got inspired after reading this post and picked up some acrylic tubing at TAP Plastics. I think the 6 foot section of tubing I used was about $1.95. I got a decent looking pipe on my second try (blew a hole in the first one), then bent and sliced up an inflow:
I'm new to the whole hobby and was amazed at how the funnel affected the water flow. I got impatient and bent the inflow without packing it with salt. That's why it didn't turn out as smooth on the corners.
I've even tried making an inline diffuser:
I haven't tried it out yet, still building the pump/filter...
I don't want to jack your thread, just demonstrate a little "imitation is the sincerest form of flattery."
