chigh Posted February 22, 2014 Share Posted February 22, 2014 Hi,I have had my 4ft cichlid tank for 2 1/2 years. I use an ehiem canister 2215 and have a air bubble thing. I use crushed coral that gets moved around a lot by fish. I have only had a couple of fish die, but from aggression. I change the water every 1-2 weeks about 35%. I have polyfilter in the tank also. I clean out the filter every month. But the water smells moldy. I did a 70% water change today to try and reduce this. Is this smell normal? What can you do to reduce this?Thanks.

dazzman Posted February 22, 2014 Share Posted February 22, 2014 hard to say without being able to smell it, and i dont know what a polyfilter is.have you done a stock count? maybe there is a dead fish in there somewhere. Link to comment Share on other sites More sharing options...
Ben Posted February 22, 2014 Share Posted February 22, 2014 My water smells like NLS. What are you feeding to your fish? Link to comment Share on other sites More sharing options...
chigh Posted February 22, 2014 Author Share Posted February 22, 2014 NLS cichlid formula. Link to comment Share on other sites More sharing options...
Ben Posted February 22, 2014 Share Posted February 22, 2014 Could be the NLS you're smelling. Fill a water bottle up with tank water and take it to your local LFS and ask them to test it for you. Also ask their opinion on the smell. Link to comment Share on other sites More sharing options...
Josh Posted February 22, 2014 Share Posted February 22, 2014 I am also feeding NLS and have noticed it smells. This seems to be something that has started in the last six months or so. I have been using this food for years. Link to comment Share on other sites More sharing options...
chigh Posted February 22, 2014 Author Share Posted February 22, 2014 No it has had the smell for a while and I only recently used NLS before that it was new era green and hikari but that makes to much cloud. I just wanted to know if that was normal. Whenever I clean the tank and water spills on the room it makes my room smell so it is quite strong. I might take some in next time I go to Andrew's shop.

malawi sand diver Posted February 25, 2014 Share Posted February 25, 2014 I think it is the garlic that they add to the food that gives it that smell?I feed NLS aswell and agree for some reason the smell seems stronger lately. They did recently change their formula (resulting in the floating pellet issue). Link to comment Share on other sites More sharing options...
FullyYellow Posted February 28, 2014 Share Posted February 28, 2014 No one has asked this. So I will. Did you wash your filter every month in tank water or tap water? Link to comment Share on other sites More sharing options...
