Hello, Now I would like but also to have your say.
This all sounds very dramatic. First of all, alder cones in my experience not the best choice, they will get moldy quickly and pollute the water addition. Let’s try better with peat in a small filter. And you do not head to the PH value is going down at regular feeding alone. From experiments with vinegar I advise, as the pH value does not remain stable and very you schwankt.Wenn plants in the aquarium have and it is your survival experiments, the good, I have no plants, survive nicht.Stattdessen my water values I and peat music in my aquarium that goes very well for years. For most Paros you do not need extreme PH values just below 5 or 5 is sufficient for most species, once a week change of water is much more important
