Gday everyone :)
I would like some advice on my filtration :)
My tank currently runs with the trickle filter in the hood, I am wanting to know more about the filter media and how often it should be replaced. Im scared that by removing and replacing the media currently in the filter (coral/liverock rubble, ceramic rings, and some filter wool on top) that I will remove the good bacteria that houses it, obviously the live rock ect ect have this bactiria also but will this have any effect? How ofter do you remove and replace your liverock rubble, ceramic rings ect ect?
I have changed the wool a few times which seems to keep my water column quite clear :)
Also in regards to adding activated carbon and other filter medias to enhance or reduce certain things (phos) I have heard about people using but know nothing about (phosguard ect ect), any recomendations, do I need these?
Also currently in the tank i have a submerg filter, only small but I am starting to think that this would be better not in the tank at all, should I remove it? Will it be causing any harm?
cheers in advance!
