Different methods work in different areas, too. All the ones we've been discussing have their uses. One reason I like swamp filters is because the later portions of modular SFs are both attractive and good habitat. Once the material comes out of the algae tanks, it's far enough along that you can cycle it outside and let wildlife enjoy it. Plus some of the best plants -- sweet flags and water hyacinths -- are lovely to look at.
I like to grow water hyacinths in my tub gardens in summer. They have these amazing long feathery black roots, and their pale lilac flowers come up on spikes that look a bit like gladioli.
But then I'm fascinated with biotechnology in general. I like using things the Earth is already designed to do. Compost is another good example. It takes nature about a hundred years to make an inch of topsoil. A determined human can make a yard of compost in about two weeks, and a lazy human can do it in one growing season.
