waterchanges in the planted tank

[plantnoob]

with such emphasis being placed on the importance of consistant and stable co2 injection , i got to wondering what impact waterchanges have on things and when the best time is to do them . are they best done when the lights are off and the co2 isnt running ?

Hi, in an ideal world it would be best to do a water change before co2 comes on. I honestly don't think it matters when you do your water change. Do one at the most convenient time, if the lights are already on then so what, I've done this before with no ill effects.

I always do mine about a few minutes after the lights come on.
