Has anybody used the walstad method in a planted tank pond? I think she describes covering the soil with gravel, but if you have enough soil mixed in with dried grass like leftover mowed grass, it tends to hold together in my small container, so I don't think it needs to be covered. Also, having some plants in the soil may keep it together. My 6.5 gallon plastic beer bubbler has a plant in it, with half soil and half water, and it stays clear. I have a 33 gallon container with dried dirt and grass mixed, and after draining a couple of times, it's starting to stay clear, but the 33 gallon container I may try to put some wild yard grass in it to see if it will grow.
So has anybody thought they could line the dug area with waterproof plastic, then put dirt over it. It might just take a long time for the dirt to process, but my idea is that you wouldn't need a filter after it's processed, because the water is slimy but clear, but no algae, it's a different kind of slime.
Also, I thought it might be good to put a plastic greenhouse over the pond whether it's dug or above ground like in those places that farm fish. It seems like the rain and the dew at night would constantly rain down gasoline, which is probably why the pond needs to be changed with water periodically. I think an ideal thing would be to have a dug pond but have a cover that can cover it during rain, at night, or in the winter. I know that a greenhouse can grow orange trees in the winter if there is exposed dirt inside the greenhouse. The dirt mixes with the air and when light travels through it, just that small amount of dirt in the humidity causes the air to heat up. I think also having a pond initially will attract snakes until they realize they may not be able to get to the fish.
