Regular Member gardengirl Posted February 18, 2008 Regular Member Share Posted February 18, 2008 Okay, I've got a problem. I do regular water changes in the goldfish tanks -- like 50 percent or more per week. I rinse the filter media and change filter pads every two weeks. I just did a water change on my 37 gallon show tank on Saturday. It has three fancy tail goldfish. I have Eclipse filtration on that tank. Anyway, two days after the WC I smell something funky. It's sort of a gaseous smell coming from the tank.... I also have a 75 gallon tank in the fish room where I am growing out 7 fancy tails. That tank has two HOB filters, but when it gets close to the weekly water change I often smell funk coming from the tank. It smells like a marina down there...... I use PRIME which has a sulfur smell to it and I often double dose with the Prime at the WC because it neutralizes ammonia and nitrates. Anyway, do you ever have a funky smell coming from your tanks??? What can be done about it??? 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Lady_Dodecagon Posted February 18, 2008 Regular Member Share Posted February 18, 2008 I get a funky smell from the goldie tank, but not any of the rest (unless the snails go on poop-duty) and I think it comes from the Prime. I'm not going to stop using it tho, it does too good keeping my params in check and I don't get as paranoid about missing a water change. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member viscosity2004 Posted February 18, 2008 Regular Member Share Posted February 18, 2008 I use Prime & my tank never smells "funky." Do you think some humidity got into the nearby walls and maybe that's causing the funk? 0 Quote Link to comment Share on other sites More sharing options...

Do you think some humidity got into the nearby walls and maybe that's causing the funk? Gosh I hope not. I aired out the house today and opened up the top on the tank and the smell is dissipated now..... Still it bothers me that it only happens on the goldfish tanks.... I think it may go away when I upgrade the filtration. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Trinket Posted February 18, 2008 Regular Member Share Posted February 18, 2008 Do you have gravel or substrate in the tank gardengirl? 0 Quote Link to comment Share on other sites More sharing options...
Regular Member gardengirl Posted February 20, 2008 Author Regular Member Share Posted February 20, 2008 No. The tanks are bare bottom..... 0 Quote Link to comment Share on other sites More sharing options...

I think it may go away when I upgrade the filtration. I guess you just need more aeration where the tank is. Good luck! I just wanted to add, I don't really have a top on my tank. The only thing above it is one of those stand-alone lighting systems that don't require a hood. So perhaps the reason I don't develop a funk is b/c the surface is well aerated. Good luck on your funky woes! 0 Quote Link to comment Share on other sites More sharing options...
Regular Member terisather Posted February 20, 2008 Regular Member Share Posted February 20, 2008 I notice that Amquel+ gives both my tanks a funky smell. But, not gonna stop using it! 0 Quote Link to comment Share on other sites More sharing options...
Guest Carebear Posted February 20, 2008 Share Posted February 20, 2008 Try adding new carbon to your filters. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member gardengirl Posted February 21, 2008 Author Regular Member Share Posted February 21, 2008 I'm keeping a top open on the tanks, exposing it to more air and it's a lot better, thankfully. :-) Maybe the tanks just need more air flow. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member soky Posted February 21, 2008 Regular Member Share Posted February 21, 2008 Try adding new carbon to your filters. Is carbon something that should be replaced regularly? I know it says to replace it every month or so on the filter instructions, but they could also just want more money. Just wondering, because I'm starting to notice a strange smell as well and I've had the same carbon for about 3 months now. Maybe that's my problem? 0 Quote Link to comment Share on other sites More sharing options...
Guest Carebear Posted February 21, 2008 Share Posted February 21, 2008 I have 2 filters on my tank and I alternate changing the carbon monthly 0 Quote Link to comment Share on other sites More sharing options...
Regular Member gardengirl Posted February 22, 2008 Author Regular Member Share Posted February 22, 2008 My carbon/filter pads get changed monthly, and are rinsed every week with the water change..... I'm upgrading the filters soon so maybe that will help. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member frloplady Posted February 22, 2008 Regular Member Share Posted February 22, 2008 on another forum someone was having the same problem. She added more filtration and that seemed to help a lot. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Lady_Dodecagon Posted February 27, 2008 Regular Member Share Posted February 27, 2008 Carbon doesn't really have to be replaced, it will just turn into a biological filter once it 'dies' since it has decent surface area. I like to keep mine changed out regularly tho, and I do mine with every water change. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member 32Bit_Fish Posted February 27, 2008 Regular Member Share Posted February 27, 2008 I've heard Carbon has a life span of two to three weeks once they are started filtering the water. Carbon absorbs the bad stuffs such as the chemical in the water and it will dump all the nasty stuffs back into the tank if the carbon is not being replaced after its life. If this is true, then carbon needs to be replaced periodically. I use carbon to remove medications in the tank, this is the only time I use them in my filter. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Lady_Dodecagon Posted February 27, 2008 Regular Member Share Posted February 27, 2008 I always imagine carbon like a tall glass. Pour a stream of water into this glass and it will eventually fill up and not be able to hold any more water. At this point the glass needs to be emptied so that it can be useful again. Well, the carbon is the glass and the nasties it absorbs is the water. Once it reaches it's limit it's time to empty the glass by changing the carbon out. 0 Quote Link to comment Share on other sites More sharing options...
