Poolmaster23262 Phenol Red Indicator Solution for pH Test, No.2, 1-Ounce

I looked around at similar options for the pool test kit (probably spent way too much time!) and ended up with this one. You won't go wrong with this order.

My only gripe about the product is you have to buy this and the yellow separately for the 1 ounce size. The replacement kit of the two only come in .5 ounce bottles.

product works

Gives accurate test results & the price was right.

PH is one of the most important parts of safe water chemistry. If its off chemicals will either not work or corrosion will quickly take place be it on pool ladders of your hot tubs heater. Most important is you ! If PH is outside of limits, skin irritation or illness can occur. This product produces very accurate readings when compared with pool store computers

It came quickly and seems to work to measure pH like it should.

Great for the cost exactly what was described

does the job. wish these color pH solutions were a little easier to read; gradation from orange to rose not as easy to distinguish.
