I have been using bottom feeders exclusively for a while now. I will always use bottom feeders part time, but I would like to try and build a top feeder, because I feel as if my juice is getting tainted as I feed it, because the juice hits the atty, mingles, soaks, and then sucks back down in the bottle along with all the impurities it meets along the way, i.e. vaped on juice, dirt from catch cup, carbon from atty etc. So I would, like to hear from some of you. what are your thoughts, suggestions, or impressions regarding the use, practicality, and building of top feeders. or even if you think it is a cool Idea. btw I dont use tanks or anything by personal preference, nothing against them for others but they are just not for me. Thanks in advance!
