The water level is at the mark on the tube and I have set the bubbles to be just above the start of the neck, so that a layer of foam/bigger bubbles make their way up the neck and pop at the top. Does this sound correct? I’d take some pics except I’m away this weekend!
edit: also running two Red Sea 100micron filter socks which catch a lot of the crud. They get cleaned every 2/3 days. This could also contribute to lack of skim I guess?
