Welcome to the hobby!Hello, I'm a noob here! My tank has been running for about a month now and I have been researching when to change out the media. I have a question that may seem dumb for experienced hobbyists, but I want to make sure I do not destroy my newly cycled tank when the time comes. The packaging for the media says do not replace all media at the same time. Does this mean that I only replace 1 chamber at a time OR do I replace the carbon on both sides, then wait, and at another point in time replace the biomax for both?
and thanks to the advice on this thread I purchased the Intank Media baskets!
The safer way is to not to replace both biomax since that's where beneficial bacterial live. If you have live rocks or other porous filtration media than that's okay as long as you don't replace all of them at once.
