9015 Problems

[jerryvan]

Hello Roger--I have a 9015 Skimmer and don't think it has worked correctly since I got it. I changed aquariums on Easter weekend and cleaned the skimmer and it has not made much skimmate since. I have read the other threads and the troubleshooting in the book and checked everything that is listed and all seems to be correct. Cant figure it out.
The fellow I bought it from says to have the screw almost all the way out. Since reading this thread I have started to turn it in slowly and now it is about half way in and still no skimming.
My CSS65 made alot more skimmate but it would overflow all the time so I thought I went to the best. Help Jerry

Usually on a 9015 the screw will need to be almost all the way out. It may be the venturi is faulty if you don't get a result at this setting.

Hello--There are bubbles but they only go about 1/2 way up the cup and a little will come over but very little. I have moved the screw back out to see what happens. Thanks Jerry
