Hi all. Just received the media basket for chamber two. My nitrates keep hovering around 40 despite water changes. All other parameters look great. So I decided to get rid of the stock foam block filter and try a media basket. But I really need some suggestions on how to layer it please. There are 3 chambers but the middle shelf can come out so I have a large bottom chamber and a smaller upper chamber. And please ignore my messy office. It’s been some week!
