OK everyone, hopefully you can give me some advice. At the moment I have fitted in my 109Ltr tank a Fluval 3 Plus internal filter, which has been running for a couple of months now with no problems. However I also have in my possesion an old Fluval 403 external filter with all the fittings. I know it is an old model, but it has never been used, so should be in perfect working order. What I want to know is, seeing as my tank isn't that big, should I carry on with my 3 Plus internal filter (ie, if it works don't fix it). Or should I fit the external 403 ( Better filtration). I know that if I change over the filters, I will have to run both filters at the same time until the external filter has matured. I have no problem doing this, but would like your thoughts on wether it is a worthwhile upgrade, or if I should leave the tank as it is. Your comments will be very welcome.
Many thanks
Ian
P.S. I know some of you don't like the Fluval filter range, but at the moment, it is all I have.
