The yellow algicide works to clear it up in your pool. I have done it twice !!
The product works very well.But It was packaged with the No Mor liquid treatment & there was no protective covering gs on bottle & it was delivered upside down so it leaked on the 2 pkgs of algae treatment & I got it on my hands & it burns skin & can leave scars if bad enough .my hand was burning so I washed it off immediately & tried to tell customer service but to no avail , I hope they read this and make changes on the packaging of the No Mor product 👍

Follow the directions
I purchased a similar package at our local Pinch a Penny store. I followed the directions and it did not totally clear the mustard algae. I purchased this product and followed the directions. I cleaned the filter and started the pump. I brushed the stairs and sides of the pool and added this 5 Oz package around the perimeter. Then added 1-gallon of liquid chlorine to the pool. It was less than 24 hours and the algae was totally gone and the water was clear. Highly recommend this product.

Worked against yellow algae
Seemed to work after 1 application. Water much cleaner. Also, suggestion to all users to change your pool / spa filter after application to prevent re-contamination.

Can’t do it alone
No change. In fact, it’s worse. I read many reviews that it not only requires a good amount of these packets, but it also requires shock to really make a difference. With a saltwater pool, we don’t want to damage anything with massive chlorine. This said it would work.
