that is not normal. Does your drop checker have a blue color when you started? Either you have water went in there or something. Mine ever change color other than blue and green and yellow.

Some types of drop checkers can leak, letting tank water dilute the 4 dKH water. That would explain what you see. What type do you have?

It's a plastic one, with an o ring to seal it. The liquid was blue when put
in the checker. Have removed it now, cleaned refilled and put back in tank.
The liquid is light blue now.
