I actually found some hard rodi water line I am going to give a try. Thank you for the response though. I misread the original post thinking it said acrylic not hard hose.
Wow, you literally do the same exact thing that I do. I guess the only real difference is that I put little loops on mine for easy hanging from under my stand.
Thanks for the DIY especially since it's a real money saver. I made about 40 of these for about $3. Thats 75 cent a piece. Do you rinse or soak these in Ro/DO Water before you replace them? My skimmer goes nuts after I replace the sock.
