Algatec Super Algaecide-Clarifier, 64 Fl. Oz Bottle

Great stuff a bit expensive but works well after you shock the pool add this with it and it removes stubborn black algae.

This is a game changer for algae in our pool. It cleared up our pool in a few days. Easy to use, easy directions, works really well

Worked as expected

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.

I treated our 96000 gallon pool with this Algaecide to help with some green algae that would reappear on the pool walls and floor. I also have some areas of black algae that I was trying to get to fade. I used 6 bottles of this product after following all of the recommendation on the label and waiting the 10 days and it did not help at all. I understand the black algae is tuff, but this didn't even touch the green algae? I could have used a much less expensive algacide but decided to pay the $300 to help with the black specks on areas and this did NOTHING. I reached out to the representative on the phone and he told me to add even more product and wait. Still nothing changed and now I can't even get a response after leaving voicemails?

My pool turned green in late July and it was still green in September. I maintained proper levels, shocked it several times, vacuumed, partial flush…. Nothing worked. I stumbled on this product and decided to give it a try. I shocked the pool and added the full bottle to my 33’ above ground pool. One week later my water was finally getting clear again. Granted, I had a lot to vacuum out of the bottom of the pool but it finally worked. While I hope to never repeat this problem I would certainly recommend this product to others. Just remember it works in combination with chlorine so shock it when you apply it.
