Hello Shifus,

My fissiden starting to turn brown after i modified my setup. Of significance, i added another external filter running in series with my current one. On top of that, i also threw in some frogbits which are thriving like crazy. I did a nitrate test and it showed between 0-5ppm. Are my filter systems + frogbits creating a nitrate-deficient environment that is causing the browning? Also, i'm using AQUASKY601. Is this too strong and is burning my fissiden?

My setup is in this thread:

Parameters:
Temp: 26 degree
Light: 8 hr a day
Co2: 1bps

TIA for your help. Is a challenge to balance between shrimps and plants....
