It is in great condition. One year old (9/03/03) and still under warranty. No holes, but drill-able if necessary (plated-glass).
Two CPR CS50 Overflow boxes:
Nine months old, in great condition (lots of coralline algae, purple, pink, green, red on them). These are hand-made welded acrylic which have stood the test of time for me. I will include an Aquamaster AW20 lifter pump with filter for each overflow. I will also include 10+ feet of flexible 3/4 PVC hose for each overflow.
$90 OBO (sold as a pair)
Flow rate 300 GPH.
3/4" bulkhead outflow
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.
