If you really need childproof lids, buy api, they have that red ring thing already.
Some of my red sea reagents have childproof caps as well. And warning labels where necessary.
And that lady who sued over the coffee deserved every penny she got..

I agree i can buy another kit. But Salifert i like better.
Im not trying to argue, although I am, but just making the suggestion to Habib.
however there is nothing illogical about warning labels. I dont know the reason why it isnt already on the bottle, but he must have his reasons, and I respect that. But common sense is actually putting a warning label. No?
Based on the Salifert alkalinity test kit instructions I have, which say that if you use 1.00 mL of titrant to reach the endpoint for 4 mL of sample then that indicates 5.71 meq/L of alkalinity, the acid in the test kit would have to be 0.02284 N (0.00571 * 4).
Just trying to steer the thread back on topic.

Why not just use the kit till you get a result you don't like and then replace it. Jeez......3 yr old test kit. Get a new one.
As for warning labels why not slap a big sign on the tank to warn children not to drink the tank water. Not to sound cruel, but if a kid has access to and is prone to downing strange bottles of liquid. Well, sorry to say that kid ain't gonna make it.

Ok gang, this is the chemistry forum, not the Lounge. Please stay on topic, and refrain from the childish remarks.

Awesome thanks Jim! Can you buy this fairly cheap?

I dont want to throw it away because it still works. And i dont have any local stores here that carry Salifert. I have to order online. So after i pay shippping and the box it cost me around 50$ for a 20$ kit. But I agree id definitely throw it away if it was easy to replace it.

I compare it to my Hanna checker which is 10.02dkh and api which is 10dkh. Salifert is 9.2dkh. It used to read the same as the other two.
Fwiw you can make your own alkalinity standard if you want. 1.135g of baking soda in 1gallon of distilled water=10dkh. Ive taken it to a pharmacist, and ive done it myself too. Both work great.

I apologize for giving you a hard time. I was on a tear on another thread and I guess it just carried over here.
The comment I made about testing till you don't like the result was because I was reminded of a talk Rich Ross gave about phosphates. And he asked "how many people have tested for ???" Then he said "how many people didn't like the result and retested and got a better answer" lol. Just reminded me of that.
I some times forget all the things we can do like diy alk standards. And I think I take for granted that I can just go to a store 10min away and get whatever I need.
