Bit late replying sorry. If you trickle the water through the Charcoal that should work. I've made a few filters to do that. All you need is a piece of about 3-4inch pipe, plastic is ok. Make about 12in long not critical. Cap the ends with screw on caps and fit a hose tail. Fit a medium to fine filter so as not to wash your Charcoal out. I used fish tank Charcoal. The process relies on the surface area of the Charcoal to remove impurities. The Charcoal will need to be renewed annually if used for drinking water. For the garden I'm not sure, it will be a calculation based on the total surface area of the Charcol,the amount of chlorine (ppm)and the amount of water through the filter. Very complicated, just taste it.We use chloramine which isn't removed by aeration. I was thinking of filling a barrel with charcoal and tap water.
Sorry people, I forgot to mention that the filter can be easily made. Cut a plastic disc to fit into the outlet end of the filter.Bit late replying sorry.

You're using this for human consumption, right? I really like the idea of building something like what you did, but I was also simply thinking of sticking a full bud bag of hardwood charcoal in my rain barrel for a couple days. Do you think that would work?Sorry people, I forgot to mention that the filter can be easily made. Cut a plastic disc to fit into the outlet end of the filter.
Drill a heap of holes in it, say 3/16". Get some fish tank wool type filter material and stuff some in on top of disc with the holes in, make it about 1-2" thick. Flush the filter until the water is clear of any Charcoal dust, now you can drink it, your coffee will taste much better

Have used it for human consumption in the past. We have been on rain and well water for the last 20 odd years. A bud bag hanging in a barrel would I suspect take a long time as the water is not flowing over the Charcoal. Bob's idea should work for watering Tobacco but I wouldn't recommend it for human consumption as we don't know what might be in the dirt or peat.You're using this for human consumption, right?
