Fish Fanatic
hi i am quite new to the hobby but have done a lot of reading on the subject i currently have a juwel rio 240 which i bought second hand.When purchased it came with the internal filter that comes as standard i have just bought a new external filter fluval 305 i know i will have to run the 2 along side each other but will it effect my water, is there anything i could do to help the new filter along i dont want the fish to be effected
