Hi All Not sure how to explain this. My AC 70 is having issues with the media basket lifting out of the filter. So what seems to be happening is that the foam block (media) at the bottom is getting pushed up and there is about a 1 inch space between the bottom of the filter and the media block. I can push it and all other media down and start the filter and it just floats back up. When this happend water comes out of tthe top of the filter, so the only way I have found to some what fix it was to put an elastic around the filter to keep the top held down and this stops it from pushing out the top. Here are the questions I have. Also a side note, I have had this filter for around 2 months and it just started to happen a few weeks ago. Any idea why this happens? Is there any thing I can do to stop it? Has anyone else had an issue like this? Thanks in advance for any replies.
