As I wrote earlier in the thread, I am now using an Aquaclear 30 HOB... I have the initial media installed (sponge, carbon, bio-max, from bottom to top)
I want to change to Sponge, bio-max, bio-max ... will I delay my cycle if I take out the carbon now and replace? Or should I just wait until the tank has cycled with the current media, change it, and monitor for spikes / cycle again if it happens when I change out the carbon?
