hello- help.... i think i stuffed up... finally got an internal filter- an "Aqua One"- does 400L/Hr- sadly neither me or the shop assistant knew anything- just put in on and the water is swirling around too vigorously...i am hopeless with amounts so only know that my tank is 60cm in length by 30 deep x 37 high- but it is only half full so actually 20cm high- i am going to take this filter back.. any suggestions other than i should have asked here first!??
