it all happened in a day, maybe 2 and i didnt notice. what caused this? i just started throwing plants in my tank. i have a 33 long, 2x37w t8, nothing else, and natural daylight (if that counts for anything).
i bought some flourish excel today and i was going to start dosing tomorrow. feel free to critique anything else wrong with my tank, i'd rather learn from harsh words rather than a light wallet.
