Hi hoping that someone can help me out with this. This is my first planted tank. It's a 29 gallon and I have two HOB filters. One is a Aquaclear 50 and the other a Aquaclear 20. I did have carbon in the filters along with sponges and the aquaclear biomax. I have since taken out the carbon and rather than replacing it with more I am wondering what might be a better option? Or should I just put in more carbon? The tank has been up and going about 4 months. We did a fishless cycle, quarratined the fish and added them in small groups so as not to overload. I want to make sure that everything stays in good order and the problem that I have right now is that with just one sponge per filter and the aquaclear biomax there isn't enough filter media in each filter. Should I add back fresh carbon, go with some type of chemical filtration medium like Purigen or just add an extra sponge or addition biological media like the biomax or some other brand? Any suggestions/advice is appreciated.
