Good product - good quality of pot

I use the ferment for the appreciation of my koi food, or as bacteria addition for the pond.
The intestinal flora of the fish should be encouraged. Even I could see that the fish after the addition of the ferment have been somewhat more agile in the pond water.
A miracle cure for algae (some claiming that) it is not.
Nevertheless, it can not hurt and is only good for the welfare of the fish and can without hesitation (because organic) are added to the pond water.
