What you see at the pond

Undigested faeces persisting after deworming usually means feed or cold, not bacteria. Check the feed store before reaching for antibiotics.

Withdrawal

4 weeks

AQUA PRAZI needs 4 weeks before harvest, counted from the last dose on day 5.

No improvement in 3–5 days

Check the feed store — damp or rancid feed is the leading cause. Cold weather also cuts digestion. Neither is solved with antibiotics.

Note

Deworm on a schedule, not on symptoms.
