Algae Break 90, 32 fl oz, Single, Non-Foaming, Non-Staining, 90-Day Algae Prevention and Control

This product is amazing! My pool co put it in the pool last year when the pool was covered with algae. It removed it and I had no more algae all season. This year they could not get this due to being out of stock. I found it on amazion and the pool is wonderful with no algae. I love this product. Yeah Algea Break 90!!!!

I have used this product for 10 years for a concrete pool and not once have I had an algae problem.

This is a premium product, but it’s going to give you the best experience to open/close your pool. Our pool company uses this product, and it doesn’t have the same foam-up that other algaecides have that you may get from a hardware store. When we asked how their product worked so well, they explained that Natural Chemistry products are their go-to. It makes opening your pool much smoother and not having to get foam to dissipate.Because you are usually using a 90-day algaecide about twice a year, opening and closing, you can search out for the best price during the year to stock up.

Only use if u need to. Puts copper in the pool which can cause staining. If u have an Aquabot, it will filter it back out.

Great algecide, used about 8oz in 5 gallon bucket (warm water) 1/2 full. 15,000 pool.Pour around pool once a month or so and no more algae problems.This the chemical that's in algaecide.

I tried many other brands, all failed to kill green algae in my above ground pool, including those from Kem-tek and in-the-swim.This Natural Chemistry 7600 is exceptional. It started working after 1 hour continuous water filtering (poured 10 oz at return, 6 oz at skim), it killed all algae overnight. Dead algae scattered the bottom of the pool. Vacuum them all through skim to sand filter. Swimming pool now looks crystal clear from top to bottom.

I would think a product name Natural Chemistry, would be safe and effective for my pool. I have had a pool for over 15 year, this years opening was tough. I have green water when I uncovered it. I used a full bottle of the normal algecide that I has used, and after 3 days of the pump running, I was not seeing much progress. I purchased this product based on good reviews and prime delivery. I dumped the whole bottle in and waited a few more days and it did not clear up the pool. I took my water to get it tested, and the informed me I had too much copper 2.0 in the water. I checked this bottle and found 14% copper. Pool company advised, lower pool by a foot, and a replacement foot, circulate, lower a foot, add a foot. Recheck still too high 1.5. $100 worth of additional product, plus device placed in the pump skimmer to remove the copper, will know if that removes the copper in a couple of days. Pool company tells me I need to get the copper out before proceeding on getting my pool open. Avoid this product like the plague.

This product does as it says, my pool is 11,000 gallon and it was green with algae to the point that i could not see 5" into the bottom, I poured 1 bottle in and run the circulation pump, the second 2 day it was clear of the algae. You must use cholrine with this product. I used cholrine tabs.
