he he.. well the plan are in my head.. i do lots of research and came up with my own simple but seemingly good skimmer.. 2 most important thing about skimmer it bobble size (many smaller bubble has more surface area then few bigger bubbles) and contact time.....( longer u can keep bubble in the reaction tube= more skimmate to attach to the bubble)... so i was going to make a recirculating needle wheel skimmer.... something like the turbofloter i have just simpler and a lot bigger... he he he... dont know when ill make it but i will eventually....
