Pattern Name: Algaecide
When i opened the pool in April, the pool was dark green with about 12 to 18 inches of visibility. Water samples were green, even 2 inches of water in a white bucket was lime green. I poured the entire 64oz bottle into the pool (33,000 gal) with the pump running. I also dumped in about 9 lbs of baking soda and 3 lbs of soda ash; the PH was below the bottom of the testing scale and the alkalinity was around 25 ppm (2 drops of taylor #0009) i saw a difference about 24 hours later and the pool was cloudy white in 36 hours. One normal pool shock later, the pool was crystal clear in 4 days from opening. There was a bit of foam for 2 more days, but that went away. This algaecide is the best i have ever used.

When it comes to eliminating algae, you're not going to do it without CHLORINE. No matter the product, you're going to need to raise your chlorine to shock level and keep it there. Then, add this product. This is discussed in the instructions that you may read only after you've purchased this product or may never read, dump this product in your pool, and then be annoyed because it doesn't work. Don't even get me started on the "yellow" products. At least when compared to the "yellow" products, this one still allows for an accurate chlorine reading after its been added to your pool and you don't have to drain your pool to get rid of it. Overall, I do like the products this company offers but wanted to provide full discourse for them on this one. I hope this review helps someone out.

My pool hasn't looked this good an it keeps on working. I will purchase another gallon for future maintenance. I had some very small green spots around the mosaics but the areas or patches of black algae was hard to fully remove with brushing. I add half of the bottle and 3 weeks later I added the rest of the bottle. I have no algea, black or green and the water is crystal clean. To bad it is winter here and it doesn't matter that its 80* the water is to cold to swim. No heater.

With the economy in the toilet and car prices through the roof The most expensive place you could ever want to visit is the supermarket You have to be very careful about what you buy This product that I purchased was supposed to kill algae I ran the pump for 8 hours before using the product The pool is Crystal Blue I just had some light forms of green on the surface of the Diamond Bright finish it's a 20,000 gallon swimming pool so I use the whole bottle but before I used the bottle I scrub the pool to get the algae off the surface This product did absolutely nothing I waited 12 hours and I scrub the pool again and all I got was clouds of of white powder you couldn't even see the bottom of the pool Two days later still algae at the bottom of the pool I've added two and a half gallons of 12% chlorine right before using the product and I use 12% chlorine today if you want to save yourself some money buy something else Because this product doesn't work I purchase something from Lowe's and I poured it into the pool and within less than 45 minutes You could see it cleaned everything you could watch it it was like a wave that came from the right side of the pool to the left side of the pool and everything was completely clean There was nothing left on the surface that even resembled any form of algae or green and I want to make one thing clear this pool was Crystal Clean and blue it just had a surface amount green algae in spots One true and honest review
