That said - mosses do really well in low-nutrient environments. Otherwise, shrimp keepers wouldn't have tanks filled to the rim with moss variety after moss variety.
I agree, the moss I've grown in the past didn't seem to require extra nutrients. Was actually pretty easy going.
I expect I'll be keeping the basil well trimmed...
I love the idea, but there's no such thing as a self-sustaining system on that scale. I'd do it for the fun and the novelty, but I would go into it expecting to have to add to it to keep it going.
I agree, and they don't market it as such. There's a hatch access for feeding the fish and doing top offs, and I'll be adding a heater where the air line runs. Will definitely monitor water quality.
I've seen hydroponic systems work with fish as the ferts, so I suspect this isn't that far off depending on what plants/fish load is maintained.
Kehy, it's 3g so would definitely work as a shrimp tank although I don't think bettas do well with shrimps. Maybe a small harem of female bettas.
It doesn't ship out until March, so I have time to ponder the possibilities!
