Okay, I picked up a good deal on a fluval 305 external filter the other day to replace my built in juwel filter. My question is, do I run it with the internal for a month or so so help establish bacteria or remove the carbon filter packs and replace them with the mature filter media from the internal filter?
If I put the mature filter media in the new filter am I going to have problems with ammonia/nitrite spikes, or will it carry on as if it were still in the internal filter ie not kill off the good bacteria when I swap the media over?
Also, do I have to use the carbon filter media at all, or can I just remove it?
One more question, would it be a good idea to place some normal filter floss in the top layer or do I have to go and buy the fluval water polisher pads?
I hope that all makes sense. Thanks in advance for any suggestions.
