Aquarium Advice Apprentice
hi. im going to be upgrading from a 300 litre tank to a 600 litre tank. the new tank comes with two new external filters. i already have two external filters on my current tank but they will be insufficient and too weak for my new aquarium. is it possible for me to just transfer all the media from the current filters into the two new filters to bypass any cycling? or is there a better way?
thanks
thanks
