Do you think what I can keep with this test result? Just paid for this test and not happy about it. Store, of course said their machine is good. I ask to retest everything since the result is unbelievable, but store only retest Cal using Redsea test kit and the result is 430. Store does not retest anything else.

If this is a tank with things still alive in it, the ammonia is obviously wrong. Ca pretty crazy too. Not sure what you intend to keep your Alk at to know if it is way off. Who knows about the other numbers. A test isn’t very useful if you have to retest everything to double check.
Bottom line is that it looks like a $12 lesson in the unreliability of this method of testing.

I think I sent you my test result before.
Here is my test result last week using Milwaukee for Salinity, Salifer for Cal, Alk and Mg, Redsea for no3 and po4. The result very much in line with my other test except the Alk use to be 9.
Since this test result, I only test Alk and No3 due to I tried to lower Alk to 9 and increase No3 to 15 (dose Brightwell Neo Nitro).

I understand. It can be 5-10% off but not 100% off on Calcium.

My result were pretty much out of wack too. Never going to test that again.

Maybe the person misread the readout 9 = 4 if then 401 doesn't sound horribly off.

Without the work Robert does to translate and correct the results these tests are worthless.

I’m extremely happy with salifert and they are priced well too. I used them for everything thing except phosphate and use a Hanna checker for that.

I don't think you can go wrong with most test kits out there. The differences between them will be how easy it is to do the test and what sort of accuracy you're wanting. API for instance are about as easy as can be, but their calcium test kit only gives you a range of 20 ppm, and their alkalinity range is 1dkh which is fairly large. I personally like Red Sea, simply because it's easy enough to add stuff via their syringe and they have a nice holding device so you can shake and add drops as necessary then read a card to see what value that is.
I had a recently bad experience with the Hanna auto-checker for alkalinity, supposedly very simple test, but it apparently has been reading WAY off from what I was at, and there really was no way to know this unless I did another test against it which I did initially way back when, but somehow I think the calibration on it just drifted.
If you want to go balls to the wall, you could do something like the Neptune Trident system, or one of the other auto testers out there, but these are by far and away the most expensive options.

With results that are clearly wrong, it seems shady the store even charged you for the test...

They didn't even read the numbers, they just wrote them down and handed it to @nly04 with no explanation. I would frankly expect at least a little go over of the numbers for $12, its not like that doesn't pay for the 5 minutes of time to read and interpret the results. It was my first time to AC and it looked a little busy, but still, I side with @Jonathan Chia where they should do a "smell test" before handing the results back. We will do a correlation this week against my Hanna tests.
