I bought on sale. I use pond salt after I clean out the pond or change out some water. It's good for the fish. Good price and fast delivery. Will purchase again.

I have used this Pond Salt in the past and had great success with my Koi's health. So when i found it on sale I got an extra bottle just to have. I tend to fluctuate between recommended amounts and lower amounts just to make sure that the bad bacteria never get too resistant. I have never gone wrong with any purchase I have made from Drs. Foster & Smith!

My koi and goldfish began flashing a few weeks ago. Within an hour of mixing pond salt into the water they stopped. It also helped with my string algae growth that accumulated over the winter when I had the pond covered. I would definitely recommend this product.

The cost is very reasonable and has finer granules than most products. Dissolves faster with no residue.

This was my first time using pond salt and so far it seems to help keep the water clear. My koi and goldfish are doing fine with it. I plan to continue adding it when I do water changes.

Maintaining a proper level of salt in our koi pond is essential. The only time our fish have shown serious signs of real stress was from the result of greatly reduced salt over years of water changes and extremely heavy rain. The fish were behaving so strangely that we called the koi vet out to take a look and tell us what to do. After a lot of testing he determined nothing was necessary but adding salt at 60 lbs. for our 6000 gal. pond. We did and the fish started improving immediately. Now we never let the salt level drop below the proper level.

Since I've been using this pond salt on a regular basis I have not had any sick fish. It is also very effective on the string algae that is a constant nuisance in my pond. I used to use all sorts of chemicals before I discovered the benefits of this product. I love the fact that it is all natural and very economical too! I would highly recommend you give this a try.

Salt is essential for fish health. I use this salt every year. Of course, must be carefull not to add too much. I love this brand, and the container size is very convinient.
