Hi I am setting up a 124L tank soon and want some opinions on canister filters for it? What would you go with (with a limited budget). I was thinking maybe a aquaone cf1000 but read somewhere that they are prone to leaking? Or a sunsun - everyone seems to be talking about them online positively and they are a bit cheaper? Or is it worth trying to find a second hand eheim or fluval or something. Thanks!
