What's that smell?

[Got Water?]

I have started to notice a smell. I have recently added some spaghetti algea in my refugium, would this have an odor?

[melosu58]

What does it smell like? A rotten egg smell?

[Got Water?]

No, it's not a strong odor, but a musty smell. I thought it was my protien skimmer's gunk but it's not.

You are not cycling are you?

[Got Water?]

Sorry, I'm a newbe at this. I don't know what that is. I might be. Please explain.

Hmmm... cycling is the thing you did (hopefully) when you first started the tank to establish a bacterial population. You either did it by adding a cocktail shrimp or other item to rot away, or you did it by adding fish.

How long has your tank been set up, and what's in it?

[Got Water?]

Oh, ya I did that.
My tank: Start up in June '08, 140gal.SW-30" high with 8/54 T5's, and all the other reg. stuff (refugium tank, wet-dry sump, protein skimmer, 2 power heads, 2 heaters, auto top off tank...I planned on having jawfish so I have a 6" sandbed.
What's in it: turbo snails, hermit crabs peppermint shimp, sand shiffting star fish, fire shimp, red starfish, clam
3 clowns (had 4 but I had to take 1 out) 5 green chromises, bi-colored blenny, clown goby, copper banded butterfly, pyjama fish, opussim, hawkfish, had a blue spotted jawfish (he jumped ship yesturday)
corals - bubble, fox, frog spawn, sponge, orange paddle, 3 types of mushrooms, button, chili pepper, torch, open brain, candy cane, toadstool, cauliflower

This is probably more info. than you wanted.
Am I on the right track?

[Kurt_Nelson]

Hmm... nothing you posted jumps out at me as wanting to create a musty smell. I suppose it could be something with the algae in your fuge, but I don't run one so I don't have any experience there.

You don't have water spillage collecting somewhere causing a mold/mildew problem in the tank stand, or on the floor, do you? Just thinking out loud...

[Got Water?]

No, I think all the cabinet is dry and in good shape but I'll check it out. It might be just some more moisture now with the heater running in the house. I have an exhust vent in the cabinet above my lights, think I might add another one. But that probably won't help my refug. tank. I'll have to give this more thought. Let me now if anyone has any more suggestion.

it sounds like ammonia poisoning to me did you let your tank cyle properly first. Ammonia is highly toxic to any fish. Reasons for an ammonia poisoning include a new set-up (nitrogen cycle), an interruption of the beneficial bacteria (i.e. power outage, medication, filter exchange) or a change in the bio-load, if too many new fish have been added to the aquarium too quickly.
