Fish Crazy
i'm hoping to upgrade from a 25g to about 50g in the next week and was wondering how to go about transferring over. obviously i dont want to cycle a new tank so is it ok to put all my existing water in the new tank and then top up with new? as for filters i currently have internal filter with sponge media and will be adding another internal to new tank so will the bacteria in the old filter be enough to cycle new tank??? my fish need more swimming space so i'd hate to kill them all off by doing the transfer wrong!! any help greatly appreciated for a stress-free changeover!
