I have a clean up 75 skimmer and i am having trouble setting it up it is in the sump when i turn it on i set the water line in the skimmer to where it says it should be but the cup just fills up with water then i have to dump it after 10-15 minutes, how long before i notice the skimmer doing anything useful and i dont have to keep dumping tank water back into the sump? or am i doing something wrong ?
Thanks, Ryan
