    Hey all- I leave my house very early in the morning, and have my lighting set for Noon-8pm so I can enjoy the tank for a couple of hours when I get home. CO2 is on 11am-7pm.

    Because of how early I am up, I am usually dosing the tank between 4:30-5:00 am.

    Does *when* you dose a tank relative to lights and CO2 coming on have any impact?

    I know they don't know about time, lol- but I don't know if having the lights on and CO2 going may allow/trigger them to absorb nutrients differently?

    The only reason it would matter is if your dosing something like urea, or using a particular chelated Fe that needs a lower PH.

    For example using Fe EDTA that does best under 6.5, or urea which is more toxic above 7. If your degassed PH is higher then its better to dose after the co2 has dropped the PH into a more favorable range.

    But otherwise no it doesnt matter.
