HOB surface skimming

One option you have is to create a small weir and put the intake for the HOB into it. I don't think I have any pictures but I had done this on a 20L a few years ago and it worked great. All I used was a 3" diameter section of acrylic I had, cut it to length so that it was about an inch below the top of the tank, stuck it in the corner and put the HOB intake in. It worked great. This also allows you to be very precise with your ATO as the evap shows up quick.

I can't recall the name but someone has a build thread with multiple anemone tanks made from 20 longs and they made up some internal weirs to create the same effect. I'll see if I can find and post a link.
