Hi,

just wondering if these are safe to use in my sump?

if so, i have piles that i'd be willing to part with

I don't see why not, just curious if you have the 3M part number for them? I might be interested on getting some.

sorry, couldnt get a pic loaded....

here's what it says on the box. I've been using one for the last couple weeks and just changing it out at the end of the week cause i have heaps....

everything is fine, super clear water....

5 micron would plug up in a matter of hours.

ya,

it gets pretty dark at the end of the week.

other than quick replacement, do you think there is anything wrong with going that fine?

Do these really have a steel ring retainer? That could be an issue if it is not coated in something inert.

Thanks for that. I think Rob is right about couple of hours it will be plugged. I was thinking maybe trying out some 50's.
