Great product that controled the mustard algae that was taking over my pool, the more chlorine I added the greener it got.

We were dealing with a stain on the liner all summer. We decided to buy super algaecide plus to see if it would help. Wow, what a difference! Our liner looks great. Will never buy anything else for all kinds of algae.

Only need a little bit. We added at opening and have not had to add more since - going on 2 mo. now. Well worth it to have a pool free of green.

After a lot of rain this year, had a little green start to show...put this product in and it killed and dropped it to the bottom for easy vac out as designed...I will use it again if I have too...does a great job.

I called Water Warehouse because my pool had black stains. They recommended the Super Shock Plus followed by this Super Algaecide - I brushed the stains and bam they were gone by the end of the day. Thank you Water Warehouse!
