This product is a miracle cure! Sure you can try to be very wise and find out how the manufacturer has just made. What's the point? Who wants this effort? I run my aquarium alongside and am glad that such an agent is available. The price is not low but the agent is very economical and it works. There is no better ausugeben less money for virtually ineffective preparations. I can only say that all the promised effects also occur eigenlich. A damage in the animals or plants is absolutely undetectable. All are flush Fidel! Great product!
