Ok now I'm confused 😓 which is easy to do. I made the solution by mixing 3 liters of distilled water with 3.6grams of baking soda giving me 40 dKH
solution I them took 50 ml of the 40 dKH
and diluted it with 450ml of distilled water giving me 4 dKH
. I put 5ml in the drop checker and added 3 drops of ph tester. That gave me blue which turned to blue/green when adding the co2
to the tank. Of course trying to find the link to the info again is not easy task.
