I use hypo as well, some of the biological potions we try are absolutely horrible to get out.Hyplochloride acid ( probably spelt wrong) as they use in the dairy is what we used after a dirty mix which left sprayer coated inside tank and lines etc. Picture In tank after cleaning now use the same stuff for filters and nozzles just soak in a bucket View attachment 906214
I left a bit of dilute seaweed/fish hydrolysate/ fine lime in the tank and it grew in the lines and nozzle head looked just like @Chae1's picture.
Hot hypochlorite made it cleaner than I've ever seen it before
