'OK, apparently so, as happened in the old days it was held the rainwater in a cistern would have. In my case, a barrel of 35 liters. The top layer of water to grow algae and other things, the biological filter, then gravel, sand and gravel, then into a storage tank.

I had trouble finding good information on this method. What was found, said the container had to be content, and not dry. So the question .....

Can I just let the lid of the drum opening and closing the water flow "to" Not when I'm done and keep it as wet or is there a better way.
