Overflow and Sump
Page 2 of 2
A Danner 250gph water pump, virtually hidden
behind a large clump of Hornwort, pushes water
from the sump back up to the main tank. The
water pump is positioned high in the sump so in
the event of a problem with the overflow, the
main tank won't flood. This strategy however,
doesn't protect the pump from running dry.
One humble 40w curly fluorescent "daylight"
bulb in a retro fitted strip light fixture provides
plenty of lighting for the fast growing Hornwort.
A do-it-yourself water bottle power filter in the
lower right corner keeps the sump and refugium
free of debris.
This sump and refugium system has been in
operation for several months now with no
issues. Recent water tests in the 90 gallon main
tank indicate Nitrate levels are at zero even
though the last water change was over a month
ago. Hornwort has a reputation for being good
at consuming Nitrates and seems to be living up
to it's reputation.
