I have had mustard algae for 2 years .Tried everything .Used this once and it stop it after a week.Brush & shock on Friday evening, algaecide Saturday morning vac to waste when it turns white.I did have to shock and vac twice.

Great product.. Cleared up the water in no time.

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

good value. clear strip on side is a big help to know how much to use. The best.

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.

Cleared up visible algae quickly!

Been using it for four years. Does what it says it does.

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!
