What is roughly the length of the life cycle for GDA? Is there a tell tale sign when it has completed? Lo-tech 29G, HOB filter,moderate lighting, minimal dosing, levels maintained roughly (as well as test kits can indicate:rolleyes: )as follows:
KNO3: 10-15
PO4: .5-1.5
No CO2, excel dosing 2x instructions
Current Nova Extreme 24W HO 10000K, 24 "W freshwater pink"
Temp 79
Thanks!!!
