why does my fish tank still smell2007-11-24 23:43:57

i cleaned my fish tank the other day, its a fresh water tank, and it is starting to smell for some reason and i cant figure it out. it is still extremely clean but the smell is not so good. when i cleaned it i did a full water change and everything. its a 29 gallon tank, with 2 water filters both work fine and have fresh filters. any suggestions im lost.

Answers:

Your tank smells because you tore it all down and cleaned it all out! You effectively killed off all the beneficial bacteria that have been helping keep it clean and smelling good since it was set up. The smell and cloudiness is a natural part of the cycling in of a new tank. They go away on their own once the nitrogen cycle is complete.

You can help with the odor by doing partial (30%) water changes every 3rd or 4th day and putting fresh carbon in your filter.

Never, ever do that once a tank is up and running. Only do regular (weekly) partial (25-30%) water changes to keep the ammonia, nitrites and nitrate levels at or near 0. I have tanks that have been set up for years that have never been torn down. They are all healthy and happy and smell like fresh water.

The only time you should do a tear down is if a terrible disease wipes out all your fish. Then you would do a bleach clean to kill all of the parasites or disease bacteria in the tank so they will not infect the new fish you get.

I have a hospital tank that I use for a holding tank for new fish. If they are infected with something, I try to cure it with meds. If unsuccessful, I do a 100% teardown and bleach clean. Then, I refill it with water from other tanks (seasoned) and put a filter from another tank in it, let it run for a week and then add some guppies to see if it is OK.

just buy a new one might just be the one u have

Try cleaning the whole filter unit out. Sometimes, algae witll build up in the filter itself. It can hide way down by the rotor that turns the pump. Good luck

dont do a full water change this imbalences the tanks water quality. only do small water changes 50%max once every wek or two.
