Vansful 3 in 1 Pool Spa Water Test Strips *** 100 *** strip pack

I purchased these for my hot tub. I was confused as to the application statement on the bottle ‘For medical organisation testing and analysing the water specimen’There are no instructions as to use soon idea how long to leave strip in the water.I filled my tub and put the normal amount of free chlorine in then tested it the test strip showed 6.2 pH, 0.5 chlorine and 0 total alkalinity - I was unsure so added more the reading was the same and I over chlorinated my hot tub!I don’t believe these are for pools and spa, I would avoid at all cost.Unfortunately I’ve had them awhile before I used them so cannot return.

As others have said, these test strips do not seem to be reliable. Tried to return without success and was asked if I had opened them - how else would I know if they worked! Suggest you try a better known brand, which is what I have done. Thought they would all work well and you were paying for a name but actually they do seem more reliable and that is the whole point of test strips. Would love my money back but told no.

These test strips did the job, took my a while to get used it as it’s kind of different to the ones I used

I have use an array of different water test strips but both her hindlegs ones the more accurate and easier to understand on what the water is like with the gauge on the back of the pub I would highly recommend them to everyone who has over a hot tub or pool

These give false readings, I bought them to try and added my usual amount of chemicals, readings we’re completely inaccurate. They could cause you to add way too much chemicals. I’ll stick to normal brand!

Fantastic for the price would definitely buy these test strips again

Side scales not clear to what is good it bad for hot tubs

Test strips did not work on PH only the chlorine levels
