Just took the readings right now...
Nitrate: 5 ppm
Dose with DIY co2
, excel, and flourish.
Started with some API Leaf zone today to add in extra potash and iron.
On a side note, before i did the substrate change last Tuesday, i added a Java Fern months prior i got at clearance at Petsmart. Half of the leaves were black in those plastic cylinder containers they sell them in. I figured that being Java Fern, it would bounce back after pruning the black leaves away. Anyway, i planted it behind a healthy shorter bush of JF, weeks later, the black from the base of the leaves seem to spread to my healthy (older) JF bush. The clearance JF eventually deteriorated and what ever happened to it seem to spread to the old healthy one.
I figured since i practically did a 100% water change with the substrate swap, i got rid of any potential JF diseases (if they even exist). I'm guessing that it's still lurking and it's like some type of JF fungus or disease?
Unless, I'm doing something wrong?
