Worked for me

I have been plagued with mustard algae all Summer for the second year in a row. I didn't realize that it was mustard algae. Put in 4oz of this product after totally cleaning my 10,000 gallon pool, back flushing the DE filter, replaced the DE, added two pounds of shock and some PH Up to get chlorine and PH levels to the correct levels. It's been five days now and the water is crystal clear with ZERO algae! I really think that this product works...I shall see.

Opening with heavy algae.

Opened the pool and had heavy algae. Product worked quickly and loosened it up to be able to net it out. Second treatment got me going in the right direction. Algeria on the walls began to disappear and clear up. I have an inground 40,000 gal pool.

Easy To Use Preventative

Had a 2 week vacation last year and had some algae upon returning. Some algecide and some floculant cleared it up but it seamed susceptible afterwards. I've been using small treatments weekly with no more green. Salt water, above ground, 8K gals. Just follow easy instructions.
