The carbon in my filter may be bad for my live plants?
I was doing some reading on some other site and it said that the carbon part of my hanging filter may remove elements beneficial to my live plants? Anybody know if there is any truth to this?

I cant tell you exactly what they are, you will have to wait for someone more versed in planted tank chemistry than I, but the carbon will remove certain macro, and micro nutrients that the plants need to thrive. This is especially bad if youre paying good money for a fertilizer, just to have some of it removed by the carbon.

My advice (and most everyone elses here) is to not replace the carbon from this point. After a couple weeks it wont be doing anything, as it will be used up. Then instead of replacing it, keep it on hand just in case. You never know when it will be necessary to remove medications from your water.

I just stopped using the filter with Carbon and just use Floss. It has worked fine and my water parameters are always fine when I check them so it must be doing the job as well without taking out all the "good stuff"

Agree. Carbon removes various substances, some of which are good for plants, and some of which are better removed by the plants themselves, which is why we use live plants. Nature's "carbon" if you like.
