Would polyfil be safe for filtration

So this stuff isn’t safe to use? Thought people have been using it for years?

I'm just suggesting a prudent practice, not that it cannot ever be done.

IMO, it's exactly like using tap water. It would likely be fine for most folks, until sometimes it is not.

I cop’d a humongous bag on Amazon for like $30, lasted me years. I basically added it to my socks (I used “mesh” socks) to extend the time between changes. I just threw it away…. Not to take a left turn but if you got sump space and a few pennies, go roller… its kinda akin to electric car windows, TV remotes, and microwaves; things you lived without until you used one….
