Mine only has 1 compartment on the outside box....its a Sealife System prefilter for 60/100 or prefilter 150/200. I assume its a U-tube as well as its shaped like a U....never have seen a C tube though...
Also in the instructions is says "place the syphon tube into the prefilter as shown making sure the end of the syphon tube is in the surface of the skimmer box and is not touching the bottom surface"....how do I control this?
I assume I will have to just fill the tank up as well as the overflow box and turn the power off and on to see what happens....
The sand is still sitting in the same spot it was the day I bought it from you!!
I have been remodeling the 2 bathrooms and I am JUST about finished so I am going to start on this next. Also will probably do a water change soon and get you some more CC
. Thanks again...hows the CC
in the sump?
Also do you have an overflow box or is your predrilled?
