I had a not very heavily populated 5000 gallon pond.
My deep lilies would, every year, develop sufficient foliage to lift the
tubers a foot or two off the bottom of the pond. We're talking about 18"
or longer tubers, with 100sq.ft. of pads, and dozens of blooms. If I
could have made them grow better with "food" I'd have to have been nuts to
do it!

Ok, so you think you're nuts, but the point still stands. With proper
feeding they'll do *better*.

Why would you want better? As I said to Ingrid - it's useful if you're
raising them to sell, but hobbyists just want to get the maximum number of
blooms, sufficient surface coverage and a minimum of removing and dividing.
Adding nutrients to a fish pond is not generally desirable.
