So right now I can't sleep because the filter in my tropical fish tank in my room is making alot of noise!
I did an entire full clean out earlier of my 70L tank because I had some free time and it REALLY needed sorting out. I had an old filter (aqua flow 200) which broke because there was a little bit that disconnected itself from the main air tube and I was fed up of going to my local aquarium shop to get it re-glued so today got a new filter from the store. I got a smaller pump (aqua flow 100) as the original was actually for tanks holding between 100L - 200L as sold by the fish store. The new one is for tanks between 50L and 100L
It was working fine when I first installed it according to its instructions in that you have to leave it fully sub-merged in the water except the very top where the air tube is so that the water squirts out of several holes and onto the surface to keep the water moving.
Earlier it was just humming as normal but about an hour or two ago, it started making a racket, kind of buzzing. It was rather loud and literally could not sleep. For the moment I've switched it off because I wasn't sure what else to do and at 2 o'clock in the morning, I don't fancy messing around with the filter as naturally I'm normally asleep at this time.
So 3 questions...
1) How long can I leave my filter off for? I mean if I leave it for 6 hours just so I can get some sleep should my fish be okay?
2) Why would my filter suddenly do this when I definately setup my tank correctly? Does it sound like an easy fix/ simple problem or is it more likely a fault?
3) Should I get it replaced?
I'm kinda hoping someone who knows about fish is on but if not I'll have to wing it & pray I don't kill my fish.
Oh! I got 4 neon tetras, 2 juli cory's, 1 guorami & 1 sucky loach fish (can't think of its name!!!)
