Re: Plant only product oxygen after water change
I don't think it is a deficiency, but it sounds like you could increase the CO2 in the water. Pearling after water changes is a common occurrence and it happens to most people.
I hear that water from the tap tends to have a lot of dissolved CO2 in it, though I am not entirely satisfied with this answer since the fish don't gasp when the water is changed.
Perhaps the plants pearl because the CO2 in the freshwater is uniformly added to the tank versus the CO2 added by the CO2/filter system.
