Hi, after about 8 years i seem to have developed an odour in my tank. My fluval 405 (which always had a charcoal bag in it) was replaced with eheim ecco pro 300, the media was set up by the guy in the shop, he told me to leave it alone and not replace anything for 6 months, just remove the carbon pad after 2 weeks and inspect it/ empty dirty water once a month.
Firstly the water is sparkling clear all levels are ok, it's not a nasty smell, but when i left the flap to feed them I get hit by this sort of earthy smell?
I do 30% water change every 4 days, keep the filter running, and use a gravel vac to remove any droppings.
The water coming out of the filter drops further during water change and smell get worse?
I took filter apart and it was pretty spotless. I rinsed the media gently in tank water yesterday but today smell is back.
I don't know the names for the media, the bottom tray has black plastic coils in it, the next has bio from previous filter and fluval biomax, the next one has what looks like bone tri angles? in it (substrate maybe?) and the final one has eheim bio and floss in it.
the water falls through a course sponge as is enters the can.
Should I remove part of something and crowbar a carbon bag in there?
guy in the shop seemed offended when I asked where the carbon was!
Is it the carbon, or lack of that is causing this smell?
As I said it isn't unpleasant or acrid, fish never been happier.
Iam just not used to having a smelly tank.
it's not smelling the room, so I think it builds up under the canopy.
any thoughts?
cheers.
three adult goldfish in 240 litre tank, I don't use the lights.
I also have a u4 internal filter, that I havnt been using as I have a bet with the guy from the aqaurium shop on wether the ecco pro is up to the job of cleaning my tank.
Thanks for reading.
