Since more than thirty years we have been dealing with water treatment. Our task is to return to the water what threatens to get lost: its purity.
Since January 2013 ROWA is again an independent company: ROWA Aquaristik GmbH. The industrial know-how of WEIL Wasseraufbereitung GmbH is still avaiable at ROWA. In the field of aquaristics ROWA has been leading internationally in the pet (zoo) specialized trade. Many large pet (zoo) specialist dealers and large aquariums trust us, where high requirements are set to good water quality or where special water treatment problems have to be mastered.
Furthermore ROWA products are also indispensable with water and art objects. Both for room objects and for large exterior installations a treatment of the water is inevitable, in order to maintain their attraction and beauty.
