Dry Beneficial Bacteria for Pond and Water Features, 8.8-Ounce | 98948

Q: Can this product be applied to an outdoor fish tank?

I use this product once a week in a pond that is 9 by 11 feet, and 2 feet deep. It works great!! And it only takes a little to use, so it last a long time. I love it. I'm sure if your tank had some kind of running water that created a splash of sorts (for extra oxygen, bubbles)like a waterfall would, it would work great. Doesn't have to be much, a simple hose slashing water, while adding the product would be enough.

Q: I have a bottle of this that I accidentally left in my garage over winter. Will the months of freezing temperatures destroy this product?

I don't think it's a problem. Although I live in that part of Arizona that rarely gets sub-freezing temperatures, we had a few frost warnings this past winter. I keep my bottle of Beneficial Bacteria outdoors out of the weather but subject to cold temperatures. It worked as usual whenever I applied it to my pond. Since I began using this product my pond has remained clear -- no green water algae. At this time of year when a lot of plants bloom I apply a small spoonful daily to the pond and it works well.
