The Algenkiller Protect was delivered immediately after the order and given on 12.09.2013 in the supplied bag in the strong algae-affected pond water. After initial Spepsis, had no effect, I can say now, the algae killer worked. The pond water is clear to the bottom (pool depth max. 1.80 m). Wait patiently So after introducing the algae killer. It acts. Please aerate the pond well. The water lilies have until now come through everything well. Can my Kois - have retreated to hibernation in the deeper still warmer water - well observed. That means I can highly recommend.
