Sure, I would agree that my experience is unlikely to be the solution to everyone who's experiencing the air accumulation and purging with their Biomaster filters. I mean, like you say, the internet has many accounts of people with this problem and I certainly wouldn't expect all those people to be running air stones on their tanks. I wanted to share my experience of resolving the annoying & concerning air purging issue with this filter in case it worked for anyone else afflicted with the issue. When initially researching the issue online, I would regularly see all manner of labour intensive recommendations being made to resolve the issue. Recommendations such as, 'apply silicone gel to every gasket and o-ring' (many of which are tricky to access), 'dismantle all tubing and thoroughly clean it', 'shorten all tubing to the minimum length possible', .......etc, etc. Unsurprisingly, these suggestions generally didn't make any difference to the problem whatsoever. Once I'd, inadvertently, stumbled upon a much simpler and immediate solution to the issue, in my case at least, I thought it'd be worthwhile to share it and potentially save some other people from trying more frustrating attempts at a fix.
