Tip 1: In early spring, a few weeks before cleaning, add half of the autumn dose again. During spring
cleaning, when you drain away the old water, this will save you a great deal of cleaning.
Should the winter months have been exceptionally warm, the algae growth begins again and the
overwintering product is partially consumed. It has also been our experience that, if a swimming pool is not
covered during the winter, up to half of its water content is replaced by snow and rain. This means, that in
such special cases, it may be necessary to add additional overwintering product following visual inspection
of the swimming pool water.
