New ideas of doing things? That's a 1970s tank, back when fish lived short lives. It's not an experiment - I had variations on that in my teens, and I regret doing that to fish.
It's an attractive idea because it's so convenient for us, and we buy ideas that suit us. At a certain point, you have to suit the life in the tank too - to me, that's a basic responsibility.
I got part way through and had an urge to grow my hair, wear flared pants and feel optimistic. But since that was a new idea, I've gone bald and seen the down sides of several systems, including that one. It's an idea that generates a guru every 15 years or so, and tries to sound legit by calling itself a Walstad based method, without using the serious research behind that style of tank.
I've always been an aquarium nerd, and always looked into the methods proposed. That one made sense when I was 17, and failed by my mid 20s when more sensible systems were proposed. They took work (water changes) and research (adapting the aquarium to the fish, and not shoehorning the fish into inappropriate aquariums), but it has been far better.
Been there, done that, sorry to see it regurgitated again and again.
