Extensively as low dosage, no algae, no lime, cat is doing well

Actually, I've summarized the most important thing in the heading.
I made me a no Brunne, - a glass bowl with stones and shells. Despite the verwendetet BRITA - water formed in a very short time a Kalkrand on the glass bowl, which in - through evaporation - water level drops not really nice looked.
In addition, the stones and shells algae began to be set.
As I had observed that the cat sometimes also fluttered a sip from the fountain, I went in search of a remedy for lime, against algae - which nonetheless is not harmful to animals.
And I find anything with this medium because it says the following:

FOUNTAIN special PLUS freed automatically fountains and water features of lime and algae
FOUNTAIN Special PLUS is harmless to plants, animals, wells and well equipment

Because it seemed to me the required dosage according to instructions so extremely low, I contacted the hotline - landline number - and got the confirmation - yes, half a cap is sufficient. And the cap is very small.
So I revised my opinion about the price first held for very high ....
Due to the low dosage of these liters holding very long.
If you overdosed produced during operation of the pump a little foam on the surface, but this is after a few days - and next time simply tilt fewer resources into the water ...
The cat it is - after a few weeks of use of this drug - still very good ... so :-) actually harmless to animals ... Even birds can and can sip, because for which there is no danger according to the manufacturer.
From me, therefore, a strong buy recommendation and 5 stars !!!
