I had a question on when to dose aquarium fertilizers. I read from multiple sources that when dosing liquid fertilizers you should dose prior to your lights turning on. My question is if prior means there is a specific time range to aim for. All my tanks turn on between 10:30am-12pm(different tanks get different amounts of light). I usually leave for school around 7:30, at that time is it alright to dose the fertilizers then? I will be pps-pro dosing.
