when testing with strips, how do you know how much product to add to correct the water?

The strip will tell you if your Low or OK or High. Then you add which chemical by the size of your pool.Color coded strips to compare to the plastic bottle on the back of it. Very easy to use.

Trial and error. Most of the products will say on the back how much to add for your size pool or spa. Example if your PH is too high, the PH down product will say on the back how much to add to bring it down. Then you will retest after the time the product says on the back. Hope this helped

It depends what product you need to add - there are many parameters that need to be balanced out. For most products, there are guidelines as to how much to add per unit of measurement per 10000 gallons, printed on the label. The trickiest one, paradoxically, is the humble chlorine, since different brands and types will dissolve at different rates. So I usually do iterations, adjusting the chlorinaror controls and sometimes adding high-quality granulated chlorine compound to the skimmers, according to instructions, then measuring again and adjusting as I go. The results are good if you have patience. It's best to add a chemical a few times, instead of overdoing it with a large dose.

You have to use your judgement. For example, if chlorine is very low, add a lb. or two of shock. Speaking for myself, I like to keep the chlorine level on the high side.As long as pH, alkalinity, stabilizer are pretty much within OK ranges, I don't worry about it, assuming the water is clear. But, do note that if your pool water is not stabilized, you will have to use much, much more chlorine. These test strips are ridiculously easy to use. They provide all the information you need in seconds, in an easy-to-read format. Hope this helps.

Each card has four test areas for Ph, Clorine etc. Each test area changes color and on the bottle there are 6 omparison colors for each of the four. The colors indicate OK, high, low very low. The bottle does not specifically advise the quantity of chemicals to add since that will depend upon the size of the pool. They are cheap enough that you can add less than normal and test again after the pump has circulated for a couple of hours. My local pool company indicated to me that the strips are quite accurate.

Not total sure, I know I have 3 different machine here at my plant - each one requires there own test strips. I know there was a couple different number of machines for this brand that take these strips.

Given your results I suspect you are using pH paper or test strips which can be off by a full point or more when testing RO water because the water is so pure. I suggest you get a good digital pH meter to test the water's pH. Remember to test the water in a way that represents normal use. A brand new system will test more acidic than a system that has broken in and is fully pressurized. Using a TDS meter is an indirect way to infer that the system working correctly. Test the water as it leaves the RO membrane and at the RO faucet, and then compare those to the tap water. Remember, the system adds calcium and magnesium minerals which both increase the pH, and increase the TDS.

No strips needed. It uses a built-in sensor which measures K-levels form your saliva.Only thing you might need is the calibrating solution in case it gets over.

You have to read the section in the manual on how to put the paper strip into your water to test it. There should have been some test strips with the packaging. I tested my water with the strips and don't have to descale but every 6 months or so. I think the descaling is factory set to European standards where the water is harder than here in the US MJM in FL

Your best bet would be to contact the reagent supplier and try to acquire the MSDS for each chemical. If they are the same, they will work. This is a great test kit. It takes me about 5 minutes to run a detailed water test, eliminates the guess work that comes with using strips.

I don't know. All it matters to me is that it works. I tried two others before this. I test the water with water quality tester it showed around 24. You can contact the manufacturer for technical questions

You can use Stress Coat to remove the chlorine from your water. Make sure you have a way to test your water. If the ph is too low, you can add a small amount of baking soda to raise it. If the ph is too high you need to buy "Ph Down" in order to lower it. If everything else on your test strips is okay, (and your water temperatures are okay) that's all you need to do.

isn't the best way to test that to test the already filtered water afterwards?

It's the amount of water you add to the chemical solution before you apply it.

Hello Dr Reese here. The strips need only be in water 20 seconds to get the correct test. However the temperature of the water can influence the quality of the test. So the water should be at normal room temperature. Not cold or hot. Hope that helps. Dr Reese

It depends on the pH range you are most interested in. My formulations require acidification from neutral (pH7 down to pH4.5) for which these strips are perfect (note where the colors transition in rows 1 and 2). Check the color range in the illustration: where there is a transition from one color to another in any of the 4 rows is where the strips are most useful.

Yes. The color of water tested will be compared to color chart. A lot more accurate than strips.

Zoe, sorry for the delay in responding I had to find my booklet as I could not remember. This monitor also only needs .3 micro-liters of blood sample. Really like this unit but the test strips are pricey if you have to test a lot. Approximately 50.00 for 50 strips. The kit comes with 25 test strips, so you will need to order additional strips soon. Some people have tried different strips for the unit that register different from the original strips, but I have not tested or tried this.

These test strips are for chlorinated pools. Drinking water has a much lower chlorine level, even before filtering. I'd check something for use in an aquarium where the desired level of chlorine is zero

a standard litmus kit cannot accurately test the pH of water due to the chemical traces on the strip and reaction process. Having said that this pH does reliably test at 9.5
