I don't know if this is already standard practice, but so I thought I would ask.
I was considering covering the top of an IBC tank with however many 5 galleon buckets that would fit. Every bucket would have it's bottom cut out, and two 1.5" holes would be hole-sawed into the top of the tank under each bucket. Heavy duty pantyhose would have a stone inserted into each toe, their legs stuffed with peat, and pushed through the the 1.5' holes.
The waistbands would be secured to the rim of the bucket, the remained of the volume filled with potting soil and planted. Foil would act as a moisture barrier to prevent evaporation.

Now I have made many "pantie SIP's" , with one 5 gallon bucket inverted on top of the other, and zip-tied together through holes drilled in their rims. The bottom of the uppermost bucket was cut out and the volume of that bucket was taken up with pantyhose filled with potting mix. These work great so am sure of the materials, but I am not sure about the addition of fish.
I know the water will wick up the peat filled pantyhose to the roots of the plants, but I am unsure if this will deliver the nitrates to the plants enough to boost their growth and filter the water significantly.

I have also considered using a baby pool as a single large container for the growing medium, but the panties work so well and I am not sure how to integrate them into the "baby pool" design.

Any thoughts? Is this design standard, or maybe considered but discarded?

What you're trying to do is called a wicking bed. It's done often, but I've never heard of pantyhose. Nice find, that one

It should work.
