Hi,
After a few years of less my my full attention I want to start to give my tank some much needed TLC.
I dug my old JBL drop checker out of the cupboard and a bottle of 4dkH water I still have. I added the prescribed amount of 4dkH water and put in 2 drops of JBL reagent into the drop checker, however the water in the drop checker is still clear.
Do I need new reagent?
