Small quantity but product works great!
Worked fast and efficiently when I needed to lower the pH in my pool from 8.2 to 7.4. It is definitely a small package (and it does reseal very well, so do not cut below the “zip” part) so if you’re having to add pH down several times a week, I suggest buying a larger quantity of it since this only lasted me a week. However, it did what I needed it to do when I opened my pool and needed to get the pH lowered quickly before my larger jug was scheduled to arrive. My only complaint would be that there are some thicker clumps but that is pretty much any powdered pool chemical. I slowly broadcasted it across the perimeter of my above ground pool in a measuring cup (more so in front of the return jet) and ran my pump 2 hours, as instructed. Tested the pH afterwards and it was perfect! I recommend for smaller pools. 4/5 stars due to the price being a wee bit high for the very small amount of product and for the clumps. I would purchase again if I needed pH down in a pinch. Oh and adding even a tiny bit makes the pool water SPARKLE!! :)

Makes PH balance simple
Just what we needed to maintain PH. We have a lot of oak trees in our yard which seems to keep PH dropping. This is a good product and reasonably priced. Dissolves well and doesn’t damage the liner. Would buy again.

Had high pH AND alkalinity levels before using this.
My second bag within 2 months and it has slowly but surely decreased my pH level AND alkalinity levels. I've been having high alkalinity problems since I took over my tia's pool over the summer (highest was 280ppm!). With this bag, and adding the correct amount suggested weekly, I have lowered my pool's alkalinity level to 170ppm as well as balancing my pool's pH level to 7.2-7.4.

It works
I don’t know much about pool chemicals but I know I got a decent amount for a low price, and it worked to lower my pools pH

Well just as I thought, by the time you ...
Well just as I thought, by the time you add the tax it's now costing double the price from when I bought it a month ago. So apparently the price a month ago was just to draw people to their product to then increase the price dramatically. So now their just as expensive as all the other brands. Keep on looking for a reasonably priced supply.

Works great to lower pH
Arrived quickly and works great. My pH was over 7.8 and alkalinity over 220. It took 3 doses in 30,000 gallon in-ground pool but now pH is 7.4 and alkalinity is 170. Chlorine works better with lower pH. Pool looks great.

Works well
Works well. Just what you need when you need to add alkalinity and the PH goes up with it.

Great product.
Love the product. Only gave four starts because it needs more measurements for smaller pools and spas.
