This product improved water clarity and lasted until it was time to close the pool! The price was great! It was easy to use, you just pour it in.

The product worked well after I was able to convert the amount needed to use in a spa. It would be helpful if the product label had an easy to use conversion table on it.

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.

Easy to use, great for a temporary fix but not a permanent one. Pool was still cloudy after use. Good price and dissolved as it should since it’s a liquid.

I do not write reviews often, but I am just so blown away that I had to come here to write a review! I thought I would give this stuff a try after finding mustard algae in my above ground pool. I cleaned my filter, Shocked my pool, Added a gallon of this at dark (Which really was overkill because I was only supposed to use half a gallon) . Then when I got up in the morning I noticed small traces of the algae not nearly as bad before and I shocked again. Later in the day it was completely gone. Not a trace. I was waiting to write a review because I have heard that it’ll disappear and come back, but I have not seen a trace in a couple of days. If you do it the correct way it will work! I am so happy with the results! I’ve spent so much on shock the past couple weeks thought I had solved the problem, but it would just come back because I did not realize it was mustard algae (new pool owner; we had one as kids but my mom did everything lol) so this is a relief to have a clean pool to enjoy for a few more weeks until the cold front starts!
