carbon filter and fertilizer/liquid CO2

[amilasiu]

Hi all,

So my fishless (so far) but planted FW nanocube is up and running... I put in some fertilizer and liquid CO2 to get plants going; however, nanocubes have a bag of active carbon, and I was wondering if this carbon will absorb the fertilizer or the liquid CO2 (since it can filter out meds and all....) should i get rid of it?

thanks

I'd remove it but hold on to it in case meds need to be removed someday (does activated carbon deactivate after it sees water?). I know carbon will remove trace. If removes macros I don't know. Still, plants need trace. HTH

I agree with czcz. The carbon will remove iron and trace. Remove the carbon.

wait so are you not supposed to use carbon for unplanted tanks either?

Not that you are not supposed to use it, rather that it is totally unnecessary in a healthy normal tank situation.

what if one had a very old filter with angel hair and carbon
is that per say...bad?
