this is exactly what i was thinking.I use the 5/8 acrylic tube from BigAls, they have other size as well, cut to desired length, drill alot of small holes then seal off one end with hot glue. I've been having it in my tank almost a year, seem to work well
You're using aquaclear right, mine is aqueon but it should works the same way, replacing the intake with the tube. Just to be sure, bring your intake to bigals and find the acrylic tube that the same size.this is exactly what i was thinking.
although its a viable option to paint black, i would prefer something clear.
did you just fuse it to your existing intake tube near the top, or were you able to bend it going into the HOB?.
is the hot glue aquarium safe?
