2011 BAR SWAP

I have a question for any BAR member. I was recently at your sap and obtained a white bottle of a solution labled kh / alkalinity std what is this item?
 
Welcome!
It is an Alk standard to use to check your test kit.
Test the standard as you would test your aquarium water.
Compare the results to the number on the bottle.
They should be the same.
If they are not then your test kit is giving you false results.

I think it's calibration fluid, if you have a alkalinity meter you can use the fluid to calibrate it.
Best only use it for test kits, not meters.
