Dosage

It is a dry product…..and dosage is on OZ?????? It would be smart and fair if you inform the dosage in an other type of measure…..like a cup….

add ozs

it may be a great product, but the instructions are to add x ounces. its a powder, so i suppose we need a scale to measure ounces? would be nice if there was translation for some kind of volume measurement like cups, tbs, tsp or whatever.

Never in Stock

I need to use this product weekly and it is almost impossible to find in Clearwater, FL stores. Publix, Lowes and Walmart are always out of stock. What seems to be the problem? Guess I’ll have to go back to using Muriatic Acid.

Easy to use

I like this MUCH better than liquid acid. This seems more expensive than acid BUT I think it’s better than it seems at first because this product seems to go further. With the granules I don’t need to worry about splashing. This is easy to use. Much easier to measure. I think the results are faster than acid also. I received this free in exchange for this review.

I finally was able to use this product the other day. It seemed I went a little overboard with the pH up. It worked as well as the pH Up product. I do recommend if anyone ever needs to lower their ph levels down.

Why?

At this time I cannot recommend this product. Love your app but it keeps telling me to add this to lower the PH. Been trying for two months and about twenty-five pounds or so and it doesn’t put a dent in the PH so my chlorine will not work. In twenty-seven years of owning a pool I have never had this problem.

Works very well!

The ph down works very good, almost too good. I used it to control a ph spike last week by following the chart on back. I have noticed that it tends to drop the ph too much by following the chart, so I half it and then check the ph again.

I normally use muratic acid to lower my PH level, but this is so much easier and accurate with a chart to refer to on the bottle based on my readings. I don’t have to worry about splashing dangerous acid onto my self or decorative stone lining my pool now with this product.

Clorox’s pool and spa pH down is a great product. It is easy to use along with the Clorox Smart Strips and Clorox app at getting the right amount of pH down to help lower the pH levels. The product dissolves quickly and helped to lower my pools pH levels.

Good but…

I usually use muriatic acid and this seems safer and easier to handle. How ever the directions for use by the app uses pounds and ounces, so you need to weigh out the amount recommended amount-who keeps a scale for that? Also it is very slow to dissolve.
