ATB has made some significant cosmetic changes to their Econo 840 cone skimmer, being called the 840 v1.5. The new design distinguishes itself from the ATB line up with a seamless molded cone body, polished CNC work, skimmate drain valve, and removable base. The molded cone body is attached to the PVC base with screws, allowing removable and complete access to the bubble plate and inner chamber for cleaning.
This is just the second ATB cone skimmer to feature the molded body, the first being the HOB Multi Use Cone. These changes offer no performance upgrades over the previous 840 line… it just looks a bit better.
Stats:
- Footprint: 8″ x 14″ footprint
- 8″ Base Diameter
- Height: 21″ (0.5″+ needed for cup removal)
- Pump: Sicce PSK 2500 based Mini Airstar
- 17-21w (25+ scfh) depending on pinwheel / mesh used
There has been confusion over the white color that the majority of the new 840 v1.5s are sporting. All ATB Skimmers are available in white upon special request. The stock ATB colors are red in the USA. If you fancy white, let them know before you pull the trigger.
