Hello! I just started my first planted tank and I guess I somehow missed in my research that carbon filters are bad for planted tanks. I've had my tank running for a couple months now, I just have a couple anubias, a couple java ferns, java moss, some frogbit and red root floaters. I'm using seachem flourish for fertilizer. I have the Aqua-tech 5-15 filter which has the carbon filter in it. Is there something I can put in my current filter as filter media instead of the carbon filter or do I need to get a new filter all together? Thanks in advance for any advice!
