Heres what I was thinking. I have a longer window sill tank, thats just one I use to grow little bugs for my baby cloud minnows, and the pipe will be verticle! Any suggestions on suitable plants? I know its not nearly enough area to fully filter the water, but some floating plants can get a dense growth. My Missus says strawberries!
Looks like it will work fine. A pond feature pump (fountain) with a coarse foam filter to stop the fleas and leaves will work (& give a little peace of mind). Aerate the water in the tank (under the roots) with a couple of wands (full length of the tank).
Pre-filter the water before it enter the plant tank, but don't clean the pre-filter very often (bet you never heard someone tell you that before

), this way the waste will breakdown by errosion and be better used by the plants.
You'll have to trellis strawberries (MMmmm), but thta's a nice spot for them. If your leaning toward edible plants .. lettuce & watercress have a good root structure, otherwise...
Floating plants: waterlettuce, water hyacynth, cattails if you can support them. Duck weed to fill in the spaces (& use for fish food). Lilies are too big for what the contribute (or take away).
Submerged plants?: Anacharis, foxtail, hornwort, parrots feather, algae.
If there is enough fish waste/ammonia you can combine both types of plants in there.
Aerate the gravel filter from the bottom also (important, water is depleted at this time from fish and plants (@ night)). Have you considered small lava rock (more surface area) instead of gravel? Some say it clogs up, but with the pre-filter that could be 2 years down the road. I keep a 55g barrel (with a lid) of it with water aging after cleaning.
This is a nice project. Especially since your DW is chiming in positively
