This is crazy…

One star is too high. Yesterday morning our chlorine levels were in the low range of ok. The last two tests, without adding any chlorine, says we are too high. Yesterday morning’s test indicated we needed new products to add to the pool. Tested the water last night prior to adding new chemicals and the test revealed that those chemicals were not needed at all. Our water is still cloudy and your application appears to be a tool for you all to get us to continually buy products that do not work.

Tricky stuff

Package said to use the app for calculating dosage. App is nithing but an advertisement. Calculating dosage is a complex task and the last thing I needed was an advertisement for an item I own. Had to use online sources and research temperature and free chlorine levels to apply proper dosage. Better off buyng this product as a raw comodety for far cheaper.

Use less than Clorox app says too.

Day one Clorox app says High pH , add 4.75 lbs of Clorox PH Down. I added 3 is. Two days later app says add PH up 2.75 lbs? I did add 1lb of chlorox shock.

PH dropped mid year. Added PH up, 2.5 lbs at a time. After 4 bottles added over several days, no change. Once it jumped up for a 1/2 a day, bUT then fell back down by the AM. Guess it’s back to the pool store for something that works.

This is horrible. Ive bought all the steps added as directed n the amount n the levels say hi next day low. Idk what to do with this water. Im not putting no more of these chemicals n wasting another 1.00. Im going to the BBB method. Bleach borax n baking soda. This is a gimmic to get u too buy. Says my ph is too low too add 2lbs of ph up. So i did n next day it said ph too high add 2lbs of ph low… Also says chlorine too high add stabilizer i added the amount they said n next day same thing it had no effect n told me too add the same amount again. Only thing im going to do now is shock when it starts to turn. This is outrageous.

I keep getting 6.8, too

After a nasty bout with algae again this summer, we switched from a non-chlorine system (Baquacil) to chlorine. The Chlorox system was recommended by a family member. Love the idea of the app, HOWEVER, I too keep getting a 6.8 reading, the same as the other reviews. I have also added a TON of the pH Up, with zero change in the reading (same as the other reviews). We switched from Baquacil due to the expense & difficulty in keeping the chemicals balanced, especially if things go awry , but so far the Chlorox system has not proven to be any more cost effective or easier to get the chemicals balanced. Frustrating and disappointing.

Good stuff!

I’ve had problems with scale buildup on my salt cell always. Up until now I just considered it a weekly chore to clean it. I have been fighting black algae that has stained my pool for years. This year I was determined to get my plaster white again. By the time I got thru pouring copper based algaecide in the pool, I ended up with blue spots in the plaster. I’ve used other metal remove products before but found them to be a hassle to use. This was simple and easy and the blue spots were gone! I had just cleaned my cartridge filter so it was ready to give the cartridges a quick rinse after using this. What I really like is a month later I still haven’t had to clean my salt cell. Definitely will keep using this. Anything to make my life easier

Worked too well?

I ran a water analysis on July 2. The treatment plan called for 1 pound of PH Down. I did so. I ran a water analysis on July 8. The PH went too low and the treatment plan was to add 0.75 pounds of PH Up. So, the PH Down worked too well, but I was guessing how much 1 pound was. I now assume I added too much. Note: I live in central Florida and it has been in the 90s daily, with high humidity and a blazing sun but no rain from July 2 to July 8. I also added Clorox® Pool&Spa Scale, Metal & Stain Control at the same time as the PH Down. The pool water has become cloudy. I don’t know what caused the cloudy water, but I will add Clorox Extra Blue Clarifier to clear the water.

Correcting PH

This product works great. For many years I would allow the PH level to drift below 7.2 and I constantly had issues with algae and chlorine levels. Now a days I make sure I keep the PH level within the correct range. It seems like all other levels are dependent on this one factor. Love this product. Pour it in, wait a couple of hours and recheck. If it is still low pour more in until your final PH level is within the 7.2 and 7.6 range. This product makes pool life so much easier.

Contradicting treatment plan

I am not sure if it the product or the app I don’t like. I tested and scanned using the app. Over the past few weeks I have added pH up then pH down per app instructions . Tonight I realized the package instructions and the app treatment instructions are very different. The app had me adding 2.75 pounds while the package instructions had me adding 12 ounces. For a 10000 gallon pool that is quite a difference. I am prone to think this is a ploy to sell more product. I like the ease of simple testing at home, but do not want to feel I am being taken mislead.
