Algae remover

We bought this because it was convenient and easy to use. However, I don’t see any results. There’s just not enough ingredients to kill the algae. Our pool guy recommended a 60% version that we will be buying. Kind of a waste of money that we started with this and didn’t work.

What’s with the blue water?

I’m using the Awesome Algaecide in a recirculating fountain with enormous algae growth due to the extreme hot weather. Nothing on the bottle label or on the website about the water turning blue. We’ll se what happens over the next 12 hours.

It says “Pool and Spa”

Nowhere online or on the actual bottle of the algaecide can I find how much one should put in a spa. The label clearly reads Pool and Spa. So how much do you use in, say, a 300-gallon spa?

Great product to have on hand at home at all time.

The algaecide is one of the products we really need to have on hand. It has proven efficacy on killing the algae and leaving our pool clear, specially after a rain event. I have seen a bid difference going from cloudy water to clear.

Cloudy

No directions on container or on line. used half a bottle in ten thousand gallon pool for green algae. 12 hours later, algae gone but water is cloudy. I suppose its my fault for not returning it and guessing the dosage. Based dosage on watching the video.

Cloudy

Not so happy. I used this product and my pool is a clue cloudy disaster. I have tried everything to get my pool uncloudy but nothing is working. Highly disappointed. But my alkalinity it in the range I need it to be in. I am just worried it’s not safe to still swim in because it’s so cloudy.

This product is a lot better than other products I used to use. This product surely killed algae and I was able to brush them off corners with ease. I use it weekly now and plan to use it before and after I open my AG salt pool.

This Algaecide Helped!

I’ve been a self-taught pool owner for 15+ years and I always have trouble keeping my pool clean. When I recently found myself with a green pool (again – ugh), I used the Clorox Awesome Algaecide (along with shock) and within a couple of days my pool started clearing up. I like the fact that you can see the product go into the pool at first. I will be using this some more–hopefully as a maintenance product now.

Great to fight off green algae!

Didn’t properly close our pool for the winter months, so we had a pretty good green algae situation throughout our pool. This helped combat the issue and cleared up the pool very well. I definitely recommend this product!

A must have to keep the slime away

I add a little of this to my pool every week. Guaranteed to keep algae away. Along with using shock and keeping my chemicals stable, this works 100%. I’ve never felt my pool feel even slightly slimy. This is a must to have added to your pool.

Green Water no more!

This spring was a warm one, and the pool water got away from me. You guessed it green water! Awesome Algaecide took care of the problem in the twinkling of an eye. I added shock to the pool, ran the pump for an hour, then added 16 ounces of Awesome Algaecide, continued running the pump for 24 hours. I’ve got to say, it was a great pleasure to wake up to my pool being clear, and I could see to bottom of my blue liner. I’m going to use as a preventative once a week.

Great Product That Works Very Well

Works incredibly well for us. We have a shallower plaster pool and live in the Houston area, so hot and humid. We use this once a week during the peak warmer/hot months on Wednesday’s, and do pool shocks on Monday’s. The schedule works well for us, and keeps the pool nice and clear.

New Algaecide

I haven’t tried this particular line of algaecides before this. I started this past week to get ready to open for the season and it seemed to help clear up some mildly cloudy water. This has some slightly different portion sizes and time frames than others that I have used, so that will be interesting to see how it performs.

Bye Bye Algae!

Love this product. After it rains, I add this product to the pool. Last year for some reason our pool would get algae after raining (never happened in past years). It would take a couple of days to clear up. I got this product and added it after a early morning rain shower. I was happy it did not take days to fix. This product is now my go to for algae.

Takes the Algae away

This Algaecide lives up to the Clorox name. Super easy to use. It amazed me at how quickly it worked for my spring pool opening. I had more algae than normal this year, but with Clorox Algaecide and shock we are back to crystal clear water. I recommend to anyone with a pool.

Great Algaecide

The Clorox Algaecide really helps keep my pool algae free. I usually try adding this weekly to my pool but when the temps are pretty hot and it’s been raining my pool seems to start getting algae on the bottom. I will add and extra amount of algaecide to my pool and it always gets rid of the algae. Great product

Great product for algae treatment and maintenance

This algaecide works well to clear up any outbreak that I’ve had in a few days in combination with proper brushing. I also use it for weekly maintenance to ensure I won’t have any major algae blooms. I recommend monitoring mineral levels, as this is copper based and using too much could cause consequences.
