- Bob BojorquezReally works well on my poolThis Shock works really well to clear green algae build up. Helps clear it from pool and tile. Recommend purchasing if you have an algae issue.
- NULLIt works, high cyaIt’s a great product and dies what it needs basically overnight. I wish it didn’t have such a high cya content though.
- MikeStarts working in 10 mins! Check the timestamlsOh my God I was so bad this year - We ran out of chlorine during the winter... Which is usually fine because algae doesn't bloom in the winter I've noticed.... But here we are going into spring or the desert so the days are already up at like 80 to 85° so it started blooming!
We've had it covered all winter with like one of those blue bubble covers - so I'm going to tell you the right way to use the shock because I see some people in the reviews complaining it's not working.
Step one
BRUSH YOUR POOL! It's going to be gross because your pool is basically a nasty little swamp pond and it's going to be stinky and probably slimy but brush it and loosen up all that nasty algae.
Step two
Do your best to skim it as much as you can especially around the filter inlets - Make sure your pool pump is running during brushing and skimming.
Step three
SHOCK YOUR POOL! The instructions are super clear and actually tell you to do the above step number one lol I've shocked my pool before and it not work because I didn't brush it and loosen up all the crap and I was trying to get rid of.
No I'm not doing anything other than that to prep the pool - I'm not balancing pH or adding any chemicals or whatever it's just nasty pond water getting agitated.
In my photos you'll see in just 10 minutes the shock is already starting to change the color of the pool - I know I was shocked too.
Then there's the photo of it getting more clear and that's at least 2 hours after the shock.
I used a whole bag even though that's way too much for our pool because I needed to use the big guns and get it taken care of.
I'll update my review when I've got the more photos to share I'm actually in the process of doing it right now those photos above are from like a couple hours before Im writing this review. - KayGREAT PRODUCT!!!This product is great. I use this product on my pool every week. Works just as great as the shocks you get from a pool store and you're not paying the expensive price. Very economical. It dissolves quickly and within an hour to two hours it safe to swim. It leaves my pool look crystal clear. It kills all the bacteria and algae build up. I do recommend the product to any one
- SSbest shock treat ive used everChlorox ultra blue is the best shock treat.,even better than the regular chlorox white shock.
Cost is a bit much but worth it.
