Maplenoll Setup

I have a Ariadne Maplenoll turntable given to me by a friend. He had stored it in his garage for more than a few years and was looking for someone who would properly set it up and love it! Being disabled, setting the turntable up has been a slow-moving project but its now moving to the top of my list.

When I got it, it had what I suspect is a line filter in the pipeling before the tank (and one I think after the tank). When I tried, I could not blow air through either of the filters, they seemed clogged. I looked to replace them but I obviously do not know what to buy (or where to buy them). Can someone point me in the right direction for where to buy a replacement? I have scanned aquarium sites with no luck.

I am sure once I get the tubing worked out I will have a whole new set of questions!

Thanks
