rust particles has disapear in pre-filter
After many years of problems the breeder contacted us to try a final attempt to solve his problems
most of the problems were bacterial , also rust contamination in the drinking cups , tubes and tanks.
after the first round there was already a big difference , never he had such good results in years !
alfter the second breeding round ( 6 weeks ) the results were even better.
now 7 rounds later the breeder is still very satisfied with Harsonic and his old problems are solved.
also he sees a better food conversion !
