Hi all, newbie here.
I'm building an indoor vertical garden, approximately 2m x 4 levels of guttering with a "Donkey Kong" angled approach, with water pumped from the first tank 25L tank to flow down and return to it, to be pumped back up. Initially this will contain added nutrients.
I have another two tanks of 36L, 25L and am collecting another ~30L tank.
My hope is that it is possible to setup the tanks to provide the nutrients and clean the water, without the need for filters.
I'm expecting that, if possible at all, this will involve a selection of aquatic plants and microbes, small aquatics creatures and other things, though I would prefer to avoid any fish if possible due to a family members allergy.
I have done my research and understand water bridges from one tank to the next, but I'm unclear of the steps required to ensure the salt isn't transferred from tank to tank, as I don't want that entering the plants water supply. If I can ensure the salt water stays below the bridge entry with a fresh water layer, or something similar, that will do the trick, but this is my first time doing something like this, or anything aquatic (ambitious, I know) and I accept it just may not be possible, especially with such small tanks, which are low profile to allow as many growing levels as possible.
If I have to drop salt water from the equation, so be it.
Thanks for any advice you can give, and please forgive any silly aspects to my design.
