Not sure why your garden beds are raised. Like if your not supplementing light and stacking your garden system it's always going to be more cost efficient for me to just dig a hole in the ground line it with plastic and garden in that(that is if the soil is terrible!) . Also if you were serious about water usage and reducing it why bother with soil at all? Aquaculture on such a small scale hardly seems worth it as protein can be taken from plants. Coming from both small and large scale farming I feel like your system has a lot of unnecessary aspects that don't really solve any problems, it's a nice idea but not very practical.
