I used other 'store bought' from pool supplies store that had very good rating from staff...it sucked, so I bought this 'super algae' bottle as back up...I used 1/2 bottle in 10k pool and it ate up all algae that was stubborn...I thought it was expensive but actually cheaper cuz of quality...I spent 3x more on crap stuff thinking I was saving and treating but was pool store junk. This is very good Chem to use on algae, im thinking of buying more before discontinued.

As an avid swimmer, BBQ lover, and backyard enthusiast, this In The Swim Super Algaecide is an absolute must-have for the summer months! My pool gets a ton of use between family swim days and weekend cookouts, and this product keeps it sparkling clean and algae-free all season long. It’s super easy to use — just pour it in and let it work its magic. There’s no harsh smell, no foaming, and no weird residue on the surface. I noticed a huge difference within a couple of days, and my pool stayed clear even during the hottest, busiest weeks. The 7.1% chelated copper formula really does its job — no yellow or mustard algae in sight. I love that it works equally well for above-ground and inground pools, and it doesn’t irritate skin or eyes. The stability and performance are top-notch, and for the price, it’s an incredible value — you get professional-level results without the professional price tag. Bottom line: If you love spending time outdoors and want a clean, inviting pool all summer long, this is a need, not a want. Great value for the money, durable results, and reliable protection — I’ll be keeping a bottle of this on hand every year!

Kills the green algae and leaves my skin with a nice neon green glow. Helps light the way from my bed to the bathroom in the middle of the night.

This is our go to algaecide. We’ve tried many brand over the years and this one seems to work best for us. We have a 35,000 in-ground pool, chlorine sanitized, cartridge filter with variable speed pump. This algaecide works the best for us. Every pool is different and your cleaning and filtering system and schedule varies. That being said, I don’t think you can go wrong with this algaecide.

Pool looks great! No green on steps or sides for a week. Using this in conjunction with another kind of algaecide. Not sure which one deserves credit. Maybe both together. Happy regardless!

This product works great for us, no algae. I use along with Pool RX and Burn out 73 it keeps everything under control. Arizona summers can be a struggle against algae otherwise. We have been pool owners for 6yrs. We had no idea what we were doing originally. Struggled about 2yrs. We had issues with algae, first green than mustard. L----- pool supply just kept telling us to do this and that. The amout and cost of products just kept getting bigger. So we found another pool store and were told to get a good algaecide, clean everything and shock the heck out of it. We looked at tons of algaecides, read reviews and my husband finally found this algaecide on Amazon. We added the initial dosage, 6oz for our 15,000 gallon pool than burshed down the pool and ran the pool pump for 24hrs. The next day we sprayed the pool filters clean and soaked them in a large tub of water with a half bag of Burn out 73, removed vacuum, hoses and leaf basket scrubbed them clean and soaked in the Burn out 73 shock water also for about 6hrs. Sprayed everything off again and hooked it all back up. Added 6 bags of the burnout 73 to the pool and ran the pump another 24hrs. The next day we put a pool RX in the skimmer basket and returned to maintenance. It killed the algae and we haven't struggled since. We prep our pool for winter in Fall( Oct.) I clean the filters and add 4 bags of shock and the initial 6oz of this algaecide 1 day apart at night, run pump 4 to 6 hrs each night, add chlorine tabs as needed that's it. For Summer start up (end of Apr./ beginning of May) I clean filters and at night add 4 bags of shock and brush the pool, next day add the the initial 6oz of this algaecide, next day a new Pool RX in the skimmer basket and 4 chlorine tabs in float. Running pool pump 8hrs each night in the summer. I have had no algae issues for the last 4yrs. with this maintenance combination during the summer: 4 chlorine tabs in float, 2 bags of shock and 3oz of algaecide. I do this every other week 1 day apart between shock and algaecide, and of course 1 pool rx at beginning of summer in skimmer basket. I don't even do chemical testing anymore. I have clear, clean, blue pool. I use BioGuard burnout 73 shock. Which has 73= % of Calcium Hypochlorite in each bag. Pool filters need cleaning at least 2 more times each yr.( so usually Oct.,Jan., Apr.,July). This is for a 15,000 gallon pebble tek in ground pool. It might sound like a lot of work, but once you get the algae under control the maintenance is easy. We don't struggle, we're not throwing money away and we're not adding extra unnecessary chemicals.
