Don't take this wrong, Soilfloc has a strong niche to fill, in fact I've been in touch with TJ about using some myself in my own pond. I'm looking at this from a beginning approach, as-in IF I COULD DO IT from the beginning. And I believe TJ will back me on having a sound plan to start with is better than going back and trying to fill in our short-cuts.
And, if this is a situation where land based equipment cannot get access to the basin then I would strongly recommend we get TJ involved.
