No Scrubbing
This Stock Tank Defense really works. I’ve only used 3 tablets over 3 weeks and I did not have to scrub the tank. It stays clean unless the animals put their hooves in the tank

clean your stock tank in a flash
This product is great, making cleaning the stock tank very easy and keeps the water fresh longer. I clean my tank every week and the water stays of acceptable quality for that time, and the algae that grows on the sides comes off effortlessly with a scrub sponge, leaving no residual stains or marks. Without Stock Tank Defense, the tank just won't come clean as I like, even with 10x the scrubbing. This product keeps my horses happy and saves me tremendous time in cleaning. It is the best product and totally safe for horses. My horses love their water! On the shipping from Amazon, about 1/4 of the tablets were damaged and crushed, fyi. But I would order again through Amazon due to availability and lower cost than I can find locally.

If you want clean water in tanks year round this is it.
I have used these tablets in my cattle tanks year round for 2 years now. The only thing difference is I use less tablets in the winter this keeps the bottom junk growth on my heaters . The key is to start with a clean tank. If you want clean tanks this is the product.

Kind of sort of maybe works??
We've purchase this product more than once thinking that maybe it'll make a big difference. Maybe it does. Maybe. We still have to clean the 150 gallon water tank for the horses. The claims are big but the results seem to be little. It's not pricey so we will continue to use it. Nothing beats cleaning the water every 2 or 3 days though minimum if you want clean clear water! Elbow grease says it all!

Does not work
It does not work. We put 2 the first week in our stock tank then another each week after and the water is not clear.

It works pretty good.
I used this in a spring fed water trough. It’s right in the sun and gets very green. I throw in a few of these about once a month and it seems to take care of most of the green. I’ll keep using.

Great product
This product is amazing. I added it to my 80 gallon tank and had crystal clear water five days later!

I have used this product for years. It keeps the water clean and clear thus eliminating the presence of flies and mosquitoes. Great value too.

The tablets have reduced algae in our horses' water tank. About half the tablets were broken upon arrival. For a product dispensed once weekly, blister packaging would work better than loose tablets in a jar.

Most of the tablets were broke when I received them
