Highly effective in preventing algae growth in fresh water aquariums. An initial slight cloudiness shows its effectiveness and disappears after a few days.
Should always be applied in the morning. A partial water change of 30% is recommended prior to use.
Frequent treatments may damage sensitive plans. Do not use if carbonate hardness is under 4 degress dKH. Some catfish and loaches may be sinsitive. Start with half a dose and gradually increase. If signs of incompatibility appears, change approximately 50% of the water immediately.
