Replacing Carbon with Purigen
Well, my tank hasn't completed its cycling but I already have Purigen and was curious if I should replace it with the carbon.
I am dosing Flourish, Excel, and I have a DIY Osmocote tab. Is the carbon pulling any of the nutrients from these? My plants aren't dying but they aren't exactly doing much else either. Lighting is the Fluval Edge 21 LED (18 white, 3 blue) and I just bumped up the photo period from 8 to 10 hrs a day.
Would it hurt to swap out to the purigen? I know it's recommended to wait till the tank is cycled but I'm curious. Or should I just pull out the carbon? Or leave it be?
