hey guys, thanks for all the fantastic info on this site.
i recently got a 10 gallon tank to house one black moor and one calico looking fancy goldfish. i understand this may be a bit cramped but the guys are still quite small and at this point it's all i've got room for. so this will have to do for a couple months, at which point i'll grab a 20-40 gallon tank.
my question is in regards to the maintenance of my filter. how should i go about changing/cleaning the polyster fiber and charcoal? i don't want to risk the biological filtration so i understand i'm not meant to completely replace everything. should i replace a little bit now and then and just leave the majority of the filter's contents? how often should i do this?
thanks for any information you can offer.
