Customer Review

Fast uncomplicated delivery. Commodity corresponds exactly to the description. The test values ​​in the aquarium are much better since the use of BB's. The water is now really clear and pure. In addition, the algae have decreased somewhat - although do not know if this has something to do with it.

Goods are to be recommended !!!
