Hi i have just brought my first external filter today, i brought the fluval 205 as due to the great reviews it is given. I have set it up, and i was wondering, do you guys have and advice on how often i should clean out the filter or replace the media?
Thanks
Edit: I have noticed the filter every now and again blowing out a lot of fine bubbles, i am guessing this is just the Air pockets being removed from the filter, but how long should this last for?
