Fish are friends
Fish Crazy
Hi I just want to know if anyone could shed some light on the pros and cons of internal vs external filters. I currently have a fluval u2 for my 90L tank. thanks
Basically, the reason that I prefer external filters is because;
A.aesthetically pleasing
B.to change the media and stuff, you dont get your hands wet, always a plus!
C.Internal filters are big and bulky and usually tank up aquarium space. eg. in your 90litre tank, with the u2 in it, its probably 87litres
But also by getting sucked into an external (if they are small).F.Fish can die by getting trapped behind internal filters
Well I've just this evening removed my fluval 4plus internal and set up my new fluval 305 external. The tank looks wierd without the internal now . As a first time user of an external filter I would say it makes me slightly nervous that if the external filter or any of the pipes leak it could empty the tank all over my living room floor .
