Bio/mechanical for the seasons.

I'm going add more boi area to my box. Got some 1" aeration tube cut up for bio.

I also have two bags of charcoal to add. But should I wait till spring to put in the charcoal or do it now?

Why the charcoal?

It doesn't last long at all. I only use it if I'm trying to remove medication or clear up water that was discolored from a new piece of driftwood.

I don't think I have ever used it in the pond filter.

When I got my filter it came with a charcoal pad, made the water clear like air, but plugs rapidly. I will save it for spring to scrub the old water.

I think saving it for spring sounds like a good idea
