Fishbone,
Do you have any suggestions for me? I have been injecting CO2 @2-3pps on a timer with lights on a timer for a while now and my plants looked better at first. My Amozon sword is growing tall but not really as many new leaves as I would think they should and the existing leaves are starting to turn transparent. I only have the standard API freshwater master test kit. I think I read you tested phoshate and potassium levels. I'm having trouble finding those tests at my local pet stores and on line without buying a $100 kit in which I don't need the majority of. Any suggestions? By the way with my hard water the CO2 glass drop checker has never changed colors. I'm scared to increase the CO2 injection however because the fish started looking uncomfortable when I did.
