Clorox Pool&Spa 12204CLX Calcium Hardness Increaser, 4 lb, White

I think it is a good product, however it is awkward to use for a spa or hot tub. Since the instructions are for a pool of 10,000 gallons, that's why the dosing amounts are bigger. The hot tub does not come with any instructions. The customer service is helpful if you have questions, but you should realize that this product is geared more towards pools. Suppose you had a hot tub with 400 gal and wanted to raise calcium hardness by 50ppm, you would need to add 3 1/2 oz of the product. The hot tubs they offer are a smaller size, but are likely to be more expensive.

You should be careful about Clorox's recommendations and take things slowly! Other than the fact that the chemicals and the chlorox app work together as an ecosystem, I don't have any idea how to analyze this. In addition, I am not an expert on pools I am a chemistry graduate and a DIY enthusiast for the home. My trust in the app has been violated, and I feel let down. A 16000-gallon salt water pool is in my backyard. completed a test with the chlorox app and a test strip, as well as a test kit from Taylor. There were similar things about them Considering the hardness is low, 100 is a good reading. It was recommended for use in clorox applications that 16# of this hardness increaser be added. As it sounded like a lot, I added a further We have now reached 500 on the hardness scale. It doesn't make any sense to me how that happened, but watch out! Because of this, I have given this no stars, as it is TOO effective. I am not sure how that happened, unless an incorrect test was conducted, or inaccurate recommendations were provided. Regardless of what you do, the easiest way to address this problem is to drain the pool and add more water to dilute it. Texas is crazy expensive when it comes to water, so that's not cheap here either. A pool professional might also be able to help me or I could simply buy pool water in In other words, it's not as simple as it seems! Once I have resolved the problem, I will update the review.

This is for the spa at my house. Make sure you put in the right amount. There are a lot of opportunities to mess this.

My calcium hardness was low, and this product helped me accomplish that! Do not mix it with water in a bucket before pouring it into your pool, as it gets very hot and could burn your skin. You can just spread it over the surface of the water. You can count on me to make another purchase! The price is too good to be true!.

Among all the chemicals out there for pools, I think Clorox is the best. Whether you are a new tester or you are maintaining your pool water, the app provides a guide to reading the test strips. My favourite part of the bag is that it's reversible The package can be sealed. There is a good closure on it. As expected, chemical absorbs and works as described. It may be possible to find a cheaper chemical, but you will likely require more of them if the quality is poor.

It is extremely useful It is not recommended to apply directly to a pool because then you would have to stir the solution to dissolve it. Put pre-dissolved products on first and then.

I use it in my hot tub and it works great. It was wonderful to find this product and I will be purchasing more in the future. It gets started with 13oz, and then I check later to see if more needs to be added. I've been doing it that way and it's worked for me. Although I usually don't have to add more to the list.
