I brewed it short to just under 20l, I agree though in hindsight it does seem high.SloeBrewer said:1.054 sounds high for a Wherry, should have been nearer 1.046, I think. 1.017 is a bit high for finishing, leave it a few more days and see if you can get it down to 1.014 or lower.
Don't worry about the floaty bits, it's just yeast and it will drop to the bottom if you leave it long enough. If you use a racking cane with a sediment trap, you'll leave all the bits behind anyway.
I'll look in on it mid week and see what's what.
