Very nice manifold block.
This is my 3rd manifold block addition and it is way easier than I would ever expect. The precision of the needle valve to bubble rate ratio is super nice. Its easy to adjust a general bubble rate with ease. Installation was easy,I followed this video,https://www.youtube.com/watch?v=xrXqKAJwqOU
