The overflow is what they say it is. It
is well built with tough plexiglass. The
rated flow rate is about right and it is very
easy to adjust the water level. The sponge
filter has held up for almost 2 years.
However, the C-design does cause much air to
be trapped, and you must use a RIO pump.
My first RIO burned out and I tried a
couple of other brands of pumps with venturis,
but none of them had enough power to suck the
bubbles out of the overflow. You have to be
careful not to put the pump to deep, otherwise
even the RIO can't force the air that deep
into the water. Make sure to clean the air
nozzle occasionally because it can clog.

C-SIPHON OVERFLOWS
A built-in overflow is the most efficient method of draining aquarium water to a filter. If your aquarium does not have built-in overflow, CPR Continuous Siphon Overflows/Prefilters are the best means for getting water from an aquarium to a filter system without expensive modifications to the tank. They quietly skim up to six times more water than units with tubes.
The advantages of CPR Continuous Siphon Overflows/Prefilters include:
* Adjustable water level allows you to
easily change the level in your tank.
* Black top reduces algae growth.
* Quiet operation.
* CS Overflows now feature a grated inlet instead of the fish screen previously included.
