Simply Koi and More Koi

Hi all,
Want to treat for flukes with ct at 20gms per 1000gals for three consecutive days with one weeks rest then retreat one dose 20gms per 1000gals as per duncans wright up.
Do i need to bypass my nexus or let the ct run through it as it would kill the good bacteria?
Thanks in advance, John

Any treatment needs to rub through your filter to be effective. It will knock your filter but it should recover quickly just don't feed much that is only my opinion
