So I had carbon in my filter a while ago, and once I figured it was expired and the tank was cycled, I pulled it out.
Months later... My plants have dark fuzzy algae growing on them. The pleco is probably keeping the glass, slate, wood very clean - but this just looks bad on the plants. My nitrates have been a little high and I try to do a 30% change every week to control this.
Should I just go back to using carbon? Could the lack of be what is causing the algae and the nitrates? I was under the impression that you didn't use carbon unless you absolutely needed it.
Will the carbon pull out the nutrients from the Flourish Excel that I add every once in a while?
Thanks!!
