BZT will it work in cool water,Just restarted my 3500gal pond for
spring,can i put a dose of BZT in now water is below 50 degrees F.
I live in Maryland,Harford cnty.

If my memory serves me right, 50*F was the starting point. Anyone?

Most of the bacteria/enzyme additives suggest adding it after the pond
reaches above 50F as the bacteria is more active in warmer water, although
dead plant material continues to decompose in the colder water at a slower
rate - that's why we aerate and keep a hole open during the winter to allow
the "bad gases" to dissipate instead of building up to a lethal level -
ergo, I think it would work in the colder water, although at a reduced rate
and probably not be cost efficient
