Cuts the algae build up

I use this to control algae build up in the leca water reservoir under my Alocasia and Anthurium. It's nice not to have all that build up and it hasn't bothered my plants one bit.

Keeps algae away

I use 1/4 tsp of this in my self water plant pots. Keeps the algae away and doesn't harm my plants.
