I can test this product by a family friend. And he had it really necessary. What he did not do anything to get the water in the pond clean. The filter effect was also mieserabel.
And he had already taken other remedies, the flocculated. When I visited him recently, he has just pumped out and cleaned his entire pond. As the starter bacteria came just right for testing.
The box is not filled to the brim. It is a white powder. He has complained about the packaging. The box is not the screws. If it falls down times, falls out of the content. The cover is only made up.
He took a full gestr. EL for his pond. (If in retrospect have been a bit more). This he has resolved in a watering can with water and spread evenly in the pond. It flocculated not, the agent was invisible after dissolution. 24h later, the first WOW effect. He noted clearly how the water was clear. After 48h he could look down to the floor. That was never previously possible. The fish like the now clean water.
The amount specified for the pond water is indicated per cubic liter. But who knows always exactly how much water is in his pond. I would also start with less. Increase you can still.
Our pond lovers is certainly very excited and convinced of the oasis starter bacteria and will certainly buy more.
