Filter bags safe?

[Reefer Rob]

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?

[FitoPharmer]

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

[Junmity]

the ring is covered and stays about 18" above the water line.

i just hook the bag in and let the pvc pipe run down into it.

the ring never comes close to the water.

I would be concerned with the fibre free surface treatment...what are they treating it with. Also it wouldn't take long before the salt water creeps up to that steel ring. I would never use one.

[Junmity]

Good point,

is it possible to over filter with 5 microns and starve the tank of nutrients?

[Bblinks]

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.
