The drips out of the syringe are about 1/5 of the size of the big drops (if you use the small tip that Salifert provides). Since they are dosed from a syringe they are more precisely controlled. The drops from the stock API bottle could vary (I have not found a variance, but I had the extra syringes so...).but how close do the "nuclear bomb" drops compare to using a syringe?
is it close enough to be consistent?
i'm very accurate when using my kits. i usually "bleed off" the first drop to assure uniform size.
You mean there is another way to line them up?I can tell when I'm in an electrical engineers home and pass by the electrical panel box. All the wires are meticulously lined up like railroad tracks and properly labeled inside and outside the box. :lol:
OK, I think I figured it out. I tried it first and it didn't seam to work right. Here's what I did:
Using the API Test Kit normally: 12.0 dkh
Now using the API Test with the Salifert Syringe:
1st Test: Filled syring so stopper was at 1.0 line and dripped. It turned yellow with 0.29 left in syringe. 1.0 - 0.29 = 0.71, so 0.71 x 26 = 18.46. Something must be wrong, my level can't be this high.
2nd Test: Filled syring so stopper was at 1.0 line, noticed that liquid was only up to 0.78 line. Started dripping and it turned yellow with 0.32 left in syring. 0.78 - 0.32 = 0.46, so 0.46 x 26 = 11.96. This one seams right in line with the API kit. So, I imagine that you guys are filling the syring until the liquid reaches the 1.0 line, not the black stopper.
So, it appears that this method does give a more accuate reading. Now is everybody here that has both a Salifert kit and an API kit finding that they are both reading pretty close to the same. I'm getting near the end of my kit and need to get another. I'd love to just get another API (for the price, but first want to be sure that it's a descent kit. But, it sounds like that is what people are reporting in this thread.
It doesn't matter whether the liquid reaches the 1.0 mark on the syringe or not. It's best to use the black rubber stopper as the measuring point. Just check the level before and after the titration, using the same edge of the stopper, and subtract the two to get the amount that was added to the sample.
Could I increase the resolution by just using 10mL of sample water to get .5dKh/drop?
Sorry for bumping an old thread.
