Interesting article by Nathan Hill in PFK about potential long-term sub-lethal effects of elevated CO2 and ferts, especially their effects on kidneys. Soft-water dwarf Cichlids and Anabantoids do seem more prone to bloating and respiratory trouble than most of the Characoids and Cyprinids typically kept in high-tech plant tanks, and I wonder to what extent CO2 and ferts might be involved, either by directly damaging organs or making the fish more susceptible to infections in the organs. Anybody got further info on this?
