how long do you keep a strip in water to check the acidity

The test strips is to chech the acidity of your body- its says FOR SALIVA & URINE. You can spit into the strip or a few drops of your urine will do.

Since the instructions are written in Chinese there is no way of knowing how long you're supposed to soak it. But since I was using it to test urine, I didn't let it soak. All the other brands of pH strips I have tried react immediately.

Yes. The test strip has an indicator for total chlorine or total bromine. There is also a pool and spa range for the free chlorine indicator. The test strip has a pH indicator which can also be used for spa, however, the pH range is broad, so you might want a more granular pH tester.

Get yourself some chlorine and PH test strips or test drops and check it to see what the chlorine level is. I use about two tablespoons a day with a 550 gallon hot tub. But that varies with use.

They have a long shelf life. I believe the date you are looking for is at the very bottom of the tube on the white strip.

A standard litmus kit cannot accurately test the pH of water due to the chemical traces on the strip and the reaction process.....Seriously? Those chemical traces and the reaction process are EXACTLY how pH is determined. This is like saying a speedometer can not be used to measure speed because it measures distance traveled over time...... /smh

Test the alkaline level of the water periodically after a few months of use. You can find the ph comparison chart on the internet.

Hi Mike, pH Dips have been designed to indicate whole number values for pH and you should easily be able to estimate 0.5 or half units as colors on the test strip may fall in between two whole numbers. I hope this helps. Thank you for your purchase.

PH up and pH down if you really want to but I only use this test kit. Remenber cycling a large tank can take up to 8weeks. Be very patient and test daily while cycling.

it's in roll form, so how many strips you get out of it depends on how long you cut each. you don't need the strip to be very long to test it.

No. It raises the pH balance of water to 10-11depending on how long it's left in the water. From my experience pen lasts about 30 days.

The directions suggest urine or saliva. Not sure about anything else. The strip turns a color based on the value of the ph. It gives you a numeric result when comparing the darkness of the strip (yellow to green) to the result listed on the box. Needs to be around 7 to be considered alkaline enough. Sorry not to have a better answer.

Yes. Any water. Strips are not as accurate as master test kits but are good enough to see if you have a problem. Much easier

The ph does not change. You can pick up a test kit at WalMart in the pet department to check your ph levels of your water. It will tell you if it is acidic or alkaline. Then test it again after running it through the filter. Mine stays acidic as I have soft water.

Just keep an eye on it, they don't want you to go below an inch of water in the container. Probably I empty mine about once a week.

I fill the dispenser, then adjust the openings in the dispenser depending on how the test strips read after a few days. How often you use it as well as the water's starting point (e.g. using a shocker) will affect how much you need.

I let mine sit on the spots for 5-10 minutes. If you can put a little bit of weight on it it will help the acid flow out easier and quicker.
