United Chemicals Yellow Treat 2 Pound Container

This stuff worked great! Cleaned up my yellow algae in less than 24 hours! It's something I've fought ever since owning my pool and it tends to get really bad at least once a year and I've never seen it clear up as fast as when I used this. Very happy and will buy again once I need more.

I use yellow treat whenever I start to see yellow starting to develop in my pool. This product works every time. Very effective.

I have been using Yellow Treat for several years. It works better than anything else I have tried.

I've been using Yellow Treat for years and it absolutely works.

Works great!! No more algae.

Follow directions exactly and run the pump. Cleared up algae.

My 12,500 gallon in-ground pool has had a mustard algae issue. After researching products, I purchased Yellow Treat. The instructions are simple, clear, and concise, and I followed them to at "T". After the first application, the issue was well on it's way to being resolved. A four-day vacation caused the algae to return, but I will confidently apply Yellow Treat to fully and finally resolve this issue until my next vacation.

Things not so great about it, is it DOES NOT leave a chlorine reading . product says it does GUARANTEED

I had to treat a few times bc the mustard algae was so bad! It only takes a small amt each time. The shipping was half the cost of the product.

Easy to use and it works!
