misnoma Posted September 6, 2005 Report Share Posted September 6, 2005 I have a 21L tank (that's 39x25x25cmish for Alan ) which has about 10 killie fry in it, and a sponge filter. This has been running for about a month now, filter was initially "primed" running in my 4x2x2 freshwater tank, and I was doing water changes every 3-4 days.. no Ammonia detected etc. Suddenly today I come home and the fish aren't looking too happy, I test the water and notice the water smells, and there's a trace of ammonia in the tank Silly thing was I did a 20% water change yesterday of all things. Tank is bare bottom. I pulled the sponge off the filter just before, and it _reeks_.. have rinsed it lightly in some tank water, and the smell is a lot less, but I'm well confused as to where this could have come from. Ammonia is now back to zero (thanks to a decent water change) and fish looking happy, I'll be watching it closely as.. but does anyone have any ideas as to what could have caused this? I'm not keen on overcleaning the sponge obviously, but it's definitely the cause of the smell. Quote Link to comment Share on other sites More sharing options...
Ira Posted September 6, 2005 Report Share Posted September 6, 2005 When was the last time you cleaned the sponge? Probably it got all clogged up. Quote Link to comment Share on other sites More sharing options...
misnoma Posted September 6, 2005 Author Report Share Posted September 6, 2005 This is my first sponge filter experience, so you could be well correct more used to cannister filters that you open every urm.... when they stop working Smell seems to be subsiding a bit now, so will keep waterchanging etc Cheers Quote Link to comment Share on other sites More sharing options...
