Aquascape98894 Cold Water Beneficial Bacteria for Pond and Water Features, 32-Ounce

I like the idea of helping my fish through the winter month. I am hoping this will work well

A squirt or two keeps the proper balance to keep your pond sludge down and wonderfully clear water. Detritus will build up and muddy up the water if you don’t treat your pond. Great for fall, winter and early spring in the Phoenix area.

I got this stuff because of string algae blooms over winter. This cleaned it right up and kept it nice over winter

I have a large Koi pond and you don't use regular water conditioner in the winter. This conditioner is made for cold weather. I put it in once a week. It keeps the water in good condition for my Koi fish.
