Next week I will be upgrading my reefer 250 to a reefer 425xl. The rsr250 is about 5 months old and current No3 level about 25, everything else is ok.
Should I discard the old water or just ‘top’ it up and thus reduce the final nitrate level. Is there advantage in keeping it other than cost.
Thanks
Tony
