I am still continuing with the 2 water changes per week.
I trimmed the moss a little yesterday, changed the water, cleaned the filter, added some Tropica AIO ferts, counted the fish and adjusted the flow of the filter to have better CO2 distribution.
The drop checker was not coloring green before and was turning almost yellow after the adjustments.
I lowered the CO2 bps to about 2 in order to kill the fish today as I am not at home.
Just in for information... and planning, a lot of planning
