I don't understand why a 1pH drop is advised when setting up a profile for injected CO2. For example, if the water KH is 4dH and the starting pH is 7.3, the CO2 concentration will be approximately 6 ppm. But, after a 1pH drop to 6.3, the CO2 concentration will be a staggering 60 ppm...
LED lights are on for 9 hours at maximum 40% of their capacity.
KH color test (with a Sera drop set), color change at the 7th and sometimes 6th drop, tap water is at the 8th.
Water temperature 22.5-23C.
These drop tests are not very accurate!!
