Bleach Question during Conversion

[SPILL]

Hi all, I am also doing a baqua conversion - day 2. I have read a lot of posts on here before beginning so I think I'm off to a good start, but here's a few questions;
8000 Gal. AG, DE filter
FC flunctuating wildly, (from 3 to 15) impossible to keep at 15, adding bleach at rate of about 1 gallon/hr 10 gallons a day total.
CC >20
CYA 0
Alk 125
CH 90
ph 7.4

Questions, should I be worried about the high CC? I believe this is telling me that the conversion is working and 'eating' up cl.
The DE filter is gumming up quickly, cleaned and replaced the DE today, one hour later, barely any flow, if i bump it I can get a little pressure for an hour or so. Should I by pass?

I am aware I need to keep testing and keep at it, just concerned about the filter and the CC.

Any advice is appreciated, can't wait to get off the Baq.
