To be sure, I am definitely going to leave the filtration system hooked up for next Season. As you noted, from the photo of the garden this past year - it certainly didn't hurt to use it. I am just not certain that I could recommend other folks spend $50.00 out of their pockets to replicate what I did.

"Plausible".
