This is a screenshot from a youtube video, so bare with me
does anyone know where I could get an in-line airline tube filter/canister to use for an aqualifter that I use on my HOB overflow? (Like the one pictured below). I heard BRS sells them but I can’t for the life of me find them on their website. I don’t need it to actually have a filter inside, I planned to just jam a bunch of filter floss in it and call it good
