Hi, I have a tunze 9002 skimmed in the back of a 29g biocube I have a jbj ato keeping my water level the same and up until to weeks ago it was skimming ok now its not skimming what so ever. I've tried and tried adjusting my water level and the skimmer and I've had no success. I over feed rods fish food so I know that my tanks not clean. Does anyone have any suggestions or advise?
Thanks
