I have a Nautilus 30 pump that I have been running for 8 years. It is a
very good energy efficient pump. My biggest complaint with it is the
impellers are easily clogged by debris that will get through the intake
strainer, which is also pretty fine. It needs a better prefilter to keep it
from requiring daily cleaning. In the winter, I use a prefilter made of 2
of the plant baskets, but I don't use the skimmer pad. In the summer, I use
the skimmer pad, and that does not leave me the room for the prefilter.
