all your media?
most likely it's a bacteria bloom caused by the removal of the beneficial bacteria when you replaced your old media. it's like a mini tank cycle and will clear in a few days. please do not wash new media in new tap water. you should have washed it in old tank water and mixed in some old media or at least the gunk (where loads of beneficial bacteria reside) with the new media.
