Made of chemical grade acrylic, designed
to sit outside the sump or hang on the back
of most aquariums. Doesn't need adjusting.
The PS-2 and PS-3 are power/air driven and
ozone safe.
Easy to install and maintain, they
will function at any water level within the skimmer
because they are self-leveling.
They also feature a self-draining collection cup
which is removable.
