How do you keep your scobies floating?

[Guest guest]

Ever since I started making Kombucha ( beginning of this year), my

scoby from the previous batch does not stay at the top, it will float

to the side or bottom, and a new, originally healthy, lately rather

thin scoby will form at the top. I was told that this was O.K., but I

noticed that hardly any fizz develops, I think it's because it takes

about 4 - 5 days for the liquid to be covered with a new baby scoby.

So, with my newest batch I have put little pieces of boiled cork under

the scoby from the previous batch. This works well, keeps it at the

top, and there is more fizz.

I am curious though, since I noticed some other posts here where

people write that they keep their scoby family together in the jar, or

others that they have a hard time separating scobies (never my

problem...). Do you all use the cork method, or is it that you have a

floater colony and I have a sinker colony?

Would appreciate some insight,

Thanks,
