Ok, so I decided to clean my filters and do some large water changes on my 30 litre and 64 litre tanks a couple of hours ago (also changed the gravel from white to black in my 30l, looks good!).
I noticed the filter wasn't working in my 64l so took it apart and whilst cleaning it found a dead neon tetra inside!! You might have seen my thread 'Disappearing neons' in another part of the forum, well I guess I found one! Still don't know what was happening to them, I think they must have had some sort of disease at the (not very good) LFS when I got them, rest of my fish are fine, as are water parameters etc.
Anyway, I had already moved my 4 adult (which a friend gave me recently) and 2 (remaining from LFS) young neon tetras to the 30l tank to live with my male betta, they are getting on fine.
So I plugged my filter back in in the 64l. Nothing. I have played around with it, tried the age old method of unplugging and plugging it back in etc! Still nothing. I bought the tank as a complete set up and it has a 2 year guarantee so if I can find my receipt I will be taking the broken filter back on Monday (I am working all day tomorrow) to swap it for a new one.
In the meantime, I had a look in the 30l tank to see how my neons were getting on. One missing. Hmm, I looked around the tank, and finally spotted one of the two remaining young ones stuck in the back of the filter, dead. I removed it, and took the filter out. I was keeping some guppies in there a couple of days ago and my smallest male got stuck in the exact same place, and crushed his spine and I had to euthanise him using the freezing method (another thread elsewhere on the forum). Needless to say, this filter will NOT be getting used again!
So basically, I know very little about the many different types of filters out there, having only ever bought complete set ups and still being relatively new to the hobby. Does anyone know of a good, cheapish, filter which I can use for my 30l (about 8 US gallons)? Preferably one that is not a fish killer?!! I am going to have a look on ebay now.
And how detrimental is it going to be to my two tanks which are now suddenly without filters until I can get new ones?! Not happy!
