Always in a pain to fill that 10ml bottle exactly with 10ml?

Try a volumetric pipette size 10ml. Very easy to use: stick it in your tank at the right level, cover the top with your finger, put it in the Hanna bottle. Release finger. Works perfect.

Agree'd. I ordered a hundred pack of these

EDIT: Nevermind didn't look at the pic close enough. Mine are just regular squeeze-top pipettes.

I use one of these.

I use one of these but I've noticed when I fill the Hanna tester vile with the pipettor set to 10ml it fills the vile a little over the 10ml mark on the glass. I've just been filling to the line instead. Wondering if you use Hanna checkers and have the same experience or not. I might try to calibrate the pipettor but haven't looked into that yet.

Well documented. The line on the cuvette isn't even close with every checker I have(Alk, CAL, ULR phosphorus) except the new high range nitrate. the new high range nitrate checker, the line is exactly on 10ml.

No problem to fill a little over (or under) the white line if you do it all the time the exact same way.
 
What some people fail to realize too, is the line has to be measured at the bottom of the meniscus(the bottom of the curve), not where the sides of the water line up.
 
Tried one of those.... They have a 4 tipped version that is perfect for filling ALk, nitrate, PO4, and cal checker if one was so inclined.

Works great as long as you don't tip the cuvette over. Needs some sort of cuvette stand.
 
Second tip to speed up the alkalinity test significantly:

just leave the cap off the curvette.

So fill the curvette, place it without the cap in the holder and close the lid, zero, open the lid and fill the curvette with 1ml reagent (without taking the curvette out), put your finger on the curvette so you close it and turn the whole thing upside/down a couple of times like you normally would do with the curvette only, then close the lid and measure.
