BIOGENIC DECALCIFICATION
hi all .. few questions .. i now have alkaline water .. ph is about
7.6 ... although im adding CO2 to the tank .. it still the same ..
even after water changes .. could this be caused by biogenic
decalcification (check spelling please) .. i dont have anything in
the tank that would alter ph except for the peat in my substrate ..
other parts of my substrate have gone through acid testing .. so
i think their ok .. any other factor that could affect the ph ..
PLEASE COMMENT ..
TIA
MIKE
