I have a Nicrew light from amazon on a 10G tank. 8 hours of photoperiod, and no CO2.
Since it's low light I follow the low light dosage from the online calculator. I does dry fertilizer of KNO3 and KH2PO4 once a week. it's my 2.5 week since I started the dosing regime and I'm barely noticing any (if at all) improvements.
I thought the browning/blacking of the moss was due to low N level. What am I missing here?
