ATB Standard (Econo) Cone 840 Revision 2.0

ATB Standard (Econo) Cone 840 Revision 2.0
Protein Skimmer

Like all ATB skimmers the ATB 840 Standard Cone is made in Austria. The 840 v2.0 utilizes the new Sicce Syncra pump replacing the older Sicce PSK-2500. This new pump does not suffer from many of the rotational issues of the previous model which has let ATB no long need to use the custom volute, thus lowering the cost. The ATB 840 v2.0 protein skimmers are covered by a 1 year warranty along with some of the best customer support in the hobby from ATB USA.
