No, you leave the tip on.

Rather than starting a new thread...
When you finish adding the reagent, do you squirt the rest back into the bottle or down the drain? I put the rest back in the bottle, but I don't know if there are any contamination issues with this. I wouldn't think so, but last time I switched to a new kit my reading changed and I'm wondering if this has anything to do with it.

I put mine back in the bottle. Just make sure you don't contaminate the syringe. The differences in readings between one kit and another is due to variations in reagents and probably technique.

These test kits are horrible. I have tried numerous ways to draw out liquid and always get air in the syringe. Then the dropper bottles suck. They should use something like API uses, much better consistent drops.

The air in the syringe corresponds to the volume of the tip. It doesn't affect anything. The dropper bottles have always been fine for me. All dropper bottles should be held vertically when used, though.

Ladies/Gentlemen:
I concur. Just got my new Salifert ALK kit and the dropper mechanism in the bottle is garbage. Very hard to maintain control in dispensing droplets of similar proportions..... I am switching back to API..

Agreed, the air is accounted for on the Saliefrt tips. I know the ALK test kit has had its problem with accuracy but I dont understand whats so hard about there dropper bottles?? I use CAL/ALK/MAG no problems with the dropper bottles.....

Well I just got a new Salifert alk test kit because my old one was running out, and it appears to be reading the same as my old one. So I guess putting the reagent back in the bottle wasn't hurting anything. And I have no problem using the indicator dropper bottle. I always get two equal drops. Plus I've heard that the amount of indicator used is not critical. It's just the amount of reagent that affects the reading.

That is correct. The indicator is strictly for color and a slight amount more or less will not affect the outcome of the test.

I find with most Salifert kits that you need to waste the first drop or two of reagents in dropper bottles. Once you get a bit of a vacuum in the bottle, you get consistent drops.
There seems to be enough reagent that this does not prevent you from getting the advertised amount of tests.

Some bad kits are like the Seachem Iodine. You need to keep one of the reagents in the dark(perfect for using a water test kit, with all those little parts.) And the test strip is light blue across the board, with very little variation in the color. You can tell if you have 0 iodine easily but its difficult to get an exact number...
