Hi all.... some time ago I purchased a JBL drop checker after reading a very good artical in the forum. I have now run out of the drop checker fluid and I can find no replacement. I have purchased a bottle of the KH4 fluid with the blue added but that just turns clear after being in the tank for 30 mins. On checking all the stockists I find that they nearly all stock checkers but NO fluid. Are we being conned regarding the fact that it is required to use a drop checker or am I looking for the wrong thing and why is it not possible to obtain JBL refills.
