what about the solution for testing??

There is no solution. The tank water is put directly on the glass and once you look through you are able to see the salinity level.

Not sure what your question is. I use this instrument to test salt level in my aquarium. Too much salt add fresh water, too little do a water change. If mixing your own water make sure to use ro/di water and test for salt levels.

While many people use distilled water, it is highly recommended to use a calibration fluid that is set at 35.0 PSU. The reason for this is, there is a high margin of error when calibrating accuracy to a figure that is far from target. If you do not have calibration solution, you can make your own. When trying to make a calibration solution of 35.0psu, it means that the sodium chloride concentration is 3.65 (weight %). What that means is, for every 3.65 grams of sodium chloride (morton's iodized salt) there needs to be 96.35 grams of purified fresh water (distilled is ideal). To increase accuracy of the solution, my recommendation is to mix it in a greater multiple of the above amounts, i.e. 79.3g of salt mixed with 2104g of distilled water. That solution should be just about 35.0 PSU, or target saltwater salinity.

If you are referring to the calibration solution, I just used ro/di water and made sure it wasn't registering any salinity.

Most pet stores sell some type of bottled or boxed ocean water that has been purified. You can use this to calibrate the device because ocean water always has a specific gravity of 1.026. I recalibrate every time I use my refractometer to ensure the most accurate results.

There is no solution other than the saltwater that you testing. This device reads the salinity of the water.

To calibrate, use distilled water. You set the device to zero and thats all. You should do this once every three / four months.

Hi,I know there is a special test fluid you can buy to check every bottle of test strips before you use them to make sure they are functioning properly, never had a box longer then about 3 months and never had a problem besides once in a while an individual strip giving an error message. Maybe you can contact the company/maker of the tests trips directly to make sure before you buy. Have a great day

I remember something in the instructions about that. Believe it means the test is malfunctioning. There was a sort of reset option, but if it's been going on for 9 days, sounds like the tester is defunct. Time to swap out for a new one!

I'm interested in hearing more about the testing. Did you use speedtest.net or something similar? How far apart were your tests run, 5, 10 30 mins? I didn't experience any issues, bit I'm wondering if something about the test(s) your ran is the cause.

i hav not used it enough to test it out. maybe good to go to manufacture sight and ask at least what it potentially shoould do.

I believe yes, there is. These are not a super high quality test so there is the possibility of false results. There are 10 in the box though, so you can have the tester take 2 at a time.

I am not sure, but I would give it a try. I am out of Goof Off, if I had some I would pre-test it for you.

Same question but would like to hear from someone who is actually doing this. I may have to be my own test subject.

Same problem here. Works for testing, but on site failed to work immediately or after a few shots. Sent it back.

Can u be a little more specific on what you are trying to do? Or describe the expected result?

there is a video on you tube showing how to use this .and you should be able to find a generic post code list for these testers .

I do not know how many total. Just a few drops of solution are required for each test. I have two 30gal aquariums and the testing solutions are holding up well for me. But if you have a housefull of aquariums, I cannot speak to that. Again:just a few drops needed for each test.

There is a Control Solution that is mentioned in the booklet manual that comes with it to test the unit to make sure it is working but it does not come with it. Also, from what I have read about the other True test glucose unites online, you can get the control Solution for free by visiting their website and they will send it to you. I have not tried this however.

I don't have any idea about the testing. My skin did not like this product and I thought it had a very strong chemical smell.

just once. there are several types of test in the box but they're each designed to only be used once.

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

No you will need a seperate tester for that. Does great for everything else though.
