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.

Cause
Traces of iron from the fill-up
water (yellow-green
colouration
Traces of copper, from copper
pipes (turquoise colour)
Iron content in fill-up water
Manganese content in fill-up
water
Murkiness caused by
c) colloidal, organic
impurities

in hard water (limescale)
Bonded chlorine present in
water (chloramine)
Heavily foaming algaecide or
residue of overwintering/
cleaning agent is in water
pH value too low
Remedy
Intermittent chlorination with rapid chlorine
granulate or rapid chlorine tablets, regulate pH
value, add flocculant and fresh water, run
circulating pump continually.
