  1. Worked like a charm. I’ve been battling algae all summer. Have spent $100’s on big doses of shock and the algae would be back within 2 days. I was so frustrated and had little hope that this would work. For the first time in months I can see the bottom of the pool and the whole pool is clear. Looks beautiful. Was easy to use. Just dump the amount of yellow out in the pool according to dosage. Wait 5 minutes and then shock the pool.

  2. IT WORKS. Came home from a weeks vacation to mustard algae in our pool. I started by brushing, triple shocking and running filter 24 hours with no luck. Then tried Clorox algaecide product with no Luck. Bought this product, followed instructions to the T, woke up and ITS GONEEEEE! Mid day now with no signs of it creeping back in 🤞🏼 the chlorine again after 12 and 24 hours is important! Literally a miracle in a tub!! Will def buy again! Last picture is 12 hours after application !

  3. Works. It definitely did the trick on the first try, but for our small above ground pool we will only get to use this twice. So it is a bit pricey for what you get.

  4. Got some of the yellow out. Helped a lot. Took 3 rounds but it worked

    Pay attention to product size. I don’t think product size is clearly adequately advertised.Did not kill mustard algae on first application,followed directions exactly as stated.

  6. AWESOME. If you have yellow or mustard algae you NEED this product. I have a small 10 ft round by 30 inches deep above-ground pool. I live in Southeast Texas. It is very hot here. The water is shallow and when it gets hot it stays hot. Yellow or mustard algea grows/blooms like crazy. I have tried everything. This works like a charm. In the hot summer, I use it a couple of times a week to stay ahead of the algae. When I notice a little algae I put in a dose. My water is super clear and no algae. Small pools and above-ground pools can be difficult with algae but this product works great!

  9. Very effective. We have an in ground pool which has about 32000 gallon water. I took water to a store for testing due to yellow algae and was told that I have to drain at least half of 32000 gallon water due to high reading of Phosphates (>4000) and Cyanuric Acid level. The chlorine tabs will not work effectively. The girl recommended to use Phosphates remover and Cyanuric Acid remover to treat the pool first. I spent more than $150 for both. Yellow algae didn’t go away after a week of treatment. I turned to Yellow Out. A can of 2 lb. Yellow Out did the job. Our pool water becomes blue and clear again. Highly recommended.

  11. Kills all algae. Used in our inground pool which holds around 15000 gallons. Used full 2 lbs as recommended and added chlorine as directed and ran fo 24hrs. Within a day or so all algae on pool surfaces was killed and as importantly algae in the actual water died. Pool is now clear and bright blue. Will use again as needed. Have tried other brands but this one worked the best of any

  13. Always works. Pool is green and works great to get back to clear water. On the expensive side for what you actually get.

  14. Worked well for me. Mine was bad though and I had to purchase a second time for another treatment. However, this works well and I am glad I purchased it. Easy to use instructions.

  15. Works great. I had a mustard algae issue in my pool. I used algacide twice along with vacuuming and scrubbing but it didn’t make a difference. I used Yellow Out as directed and within 2 days all the algae was gone, without scrubbing! Highly recommend.

  16. Gets the yellow algae out quickly. This product works very well. I add the entire container for my size of pool and within a couple of hours the yellow is gone!!

  17. GOOD PRICE. DOES THE JOB ADVERTISED

    It Works. It works almost immediately. We have a 30k gallon pool. Just make sure to get enough for the amount of water you have in your pool that makes the difference.

  19. Pool Chemicals. Cleared right up

  20. Good product. Easy to install
