Aquarium smells moldy?

[BartokTheDog]

Hey all,

Thanks for all of your responses to my other topic.

Water conditions are currently great, 0 ammonia, 0 nitrite, <10ppm nitrate

The tank smells a little moldy - is this a bad sign or normal?

If it smells bad then there is a water quality issue, rotten food, dead fish etc. if it just smells earthy then its OK. Aquarium water does have a smell but not an offensive one. HTH

Our water/tank stinks 'fishy' too. I wonder why. We have cleaned it on regular schedule, everything tests fine. Hmmm.
