I soaked my lil reflux still with extension tower in citric acid to make it all nice and shiney inside i was gettin greeny/blue floaty bits (copper sulphides i think).
I had it soak for 2 days same with all the copper and ceramic saddles out of the extension tower and now it wont pull any better than 75% abv its quite frustaiting nothing has changed other than a good clean any ideas to why i cant pull 95-96% any more this was the 2nd run since the clean out and i dont no whats goin wrong
