Clorox Pool&Spa 43128CLX 42128CLX Pool Algaecide, 128 Fl Oz (Pack of 1)

If you have an outdoor pool, with trees nearby, this is a life saver! We have two oaks that dump pollen, and turn our pool green. *Weekly pool service isn't enough* depending on the season. - This really helps maintain our pool in between pool service visits, along with chlorine.

This pool was green and you couldn’t see the bottom 48 hrs ago! I’m new to pool maintenance but I plan on using the maintenance amount each week going forward. It’s affordable and works great!

If people are complaining this doesn’t work, it is because they have a different issue than this is meant for, or they are just not doing it right/lazy. It also needs a few days to work, and kept up on. It works for the mustard algae. Not sure about black or red, I don’t have that issue.I suggest buying two of these jugs right away. Wait until early evening. Pour a whole container in (spread out amongst the pool, pour some directly in the skimmer too) and sweep your pool really good. Get all the green. Read the instructions. Get your ph correct and then Shock the pool. Put a pack in, wait two hours and put another one in. Run the filter over night. Give it a couple days, and you will probably see some algae growing in the spots you missed. Sweep again and make sure to get those spots. Be sure to get into all the nooks and crannies with a smaller brush too (do it right! If you don’t it will just multiply) Put another half a container in and another shock pack. After a couple more days, clean your filter since all that dead algae will be in there.After that, it is just maintenance. I put about a 1/4 bottle in each week along with my other chemicals. This is pretty standard procedure for ‘sanitizing’ a pool of green. If you do it right this stuff works. I have no algae growing in my pool and it is crystal clear. And I have a dog that runs and jumps in with dirty paws 18 times a day…but still no issues staying clean.

It worked, but took a long time, and I still had a little green left on the wallsShould’ve been a little stronger

When the weather warms up the water in our water feature in our backyard which is consists of two 4 and 3 feet urns or vase turns green. Before learning about this algaecide, I apply a lot of heavy duty bleach and it will clear the out the green color in few days. Sometimes, if I put too much the water will turn blue and there will be lots of bubbles. With clorox, it cleared the water in few hours. It did produce some bubbles but it was gone in two days. Right now, the water is still clear and it's looking good.
