Pet Forum / Aquaria / Marine Reef / January 2004Sailfert KH/ALK test
I was wondering if anyody new where i can find instructions for the Sailfert KH/ALK test? I seem to have lost mine. Any help would be greatly appreciated. Here is a scan of the instructions, I didn't proof the whole thing... so there might be spelling errors here and there. INSTRUCTIONS I] Add with the 5 ml syringe 4 ml of water in the test vial. For a lower resolution and more tests per kit add 2 instead of 4 ml. 2] Shake the KH-Ind dropping bottle a few times and add 2 drops in the test vial (1 drop for the low resolution mode). 3] Put the plastic tip firmly on the 1 ml syringe. And draw into the syringe the KH reagent (ensure that the end of the plastic tip is constantly submersed in the KH reagent) till the lower end of the black part of the piston is exactly at the 1.00 ml mark. There will be some air present just below the piston. This is the air which was present between the end of the plastic tip and the piston. This will not influence the test result. 4] Add dropwise with the 1 ml syringe the KH reagent to the water in the test tube. Swirl after each drop a second or two. Continue with this until the color changes from blue/green to an orange-red or pink color (whichever color is observed first). 5) Hold the syringe with the tip facing upward and read the position of the, now the upper end, of the black part of the piston. The syringe has graduations of 0.01 mi. Read the KH or alkalinity value from the table or calculate as follows. KH in dKH = (1 - reading in step 5) x 16 AIk in meq/L = (1 - reading in step 5) x 5.71 If you have chosen for the lower resolution multiply the calculated result by 2 Natural sea water has a KH of 8 dKH or alkalinity of 2.9 meq/L. KH . and alkalinity are increased safely with Salifert'sKH + pH Buffer. > I was wondering if anyody new where i can find instructions for the Sailfert > KH/ALK test? I seem to have lost mine.

Off-topic, but what software/hardware do you use to scan written things into text? I just used the software that came with my HP scanner to scan it into MS Word. There are proggies out there that have a much better word and format recognition like ABBYY FineReader.... OmniPage etc. > > Here is a scan of the instructions, I didn't proof the whole thing... so > > there might be spelling errors here and there. > > Off-topic, but what software/hardware do you use to scan written things into text? Chris, can you scan the Nitrate kit and calcium kit too ....Ive had a bit spill of saltwater iver mine!! >I just used the software that came with my HP scanner to scan it into MS >Word.

Something I've never understood. Why don't the readings obtained from the table match the readings obtained using the multiplying factors? Example: The reading on the syringe is, say, 0.40 Reading the table gives us--dKH=9.6 and meq/L=3.43 While using the factors we(I)get dKH=6.4( 0.40X16)and meq/L=2.284 (0.40X5.71) Something is wrong! (I suspect it's me somehow) Would someone PLEASE explain this.

It would seem that there is a serious omission in the instructions in step 5. The instructions states to use the "...reading in step 5". It doesn't indicate the amount used or the amount remaining, nor does it indicate that two numbers are needed to use both the table and the multifying factors. However using your imput the following is true. 1. Using the table it's the amount remaining. (0.40) 2. Using the multifying factors it's the amount used. (0.60) > because your doing it bass awkwards. > > you multiply the amount you USED. not what is left in the syringe. > > if you have 0.4, you used 0.6 > 0.6x16=9.6 there is no omission in the instructions... you just overlooked the 1 - reading. KH in dKH = (1 - reading in step 5) x 16 AIk in meq/L = (1 - reading in step 5) x 5.71 1 - .40 = .60 .60 x 16 = 9.6 1 - 40 = .60 .60 x 5.71 = 3.426 Chris > Well....that would certainly explain the difference.

What I 'saw' was #1 'dash'...'reading in step 5.' and etc. Would have caught it had they used 1.0 instead. Thx CC > there is no omission in the instructions... you just overlooked the 1 - > reading.
