I am new to this great hobby! I bought a 1.5m Aquaria tank. The tank is now in process of cycling. My concern is, I am dosing nitrifying bacteria from the start, do I leave the lights on or off? I have read that it is better to leave the lights off for a period to contain unwanted algae….but is not sure if the nitrifying bacteria will “work” if the lights is switched off! At this stage I have no live rock but to do have aragonite in the sump.
