Hi hope some one can help me?

I have a mainly sps reef tank some lps.
The tank/water has developed a smell like cat pee does any one know what it could be.

Many thanks justin.
 
How long has the tank been set up?

What are your water parameters?

Anything change recently other then the cat-pee smell?
 
Hi
No we dont have a cat! tank has been set up for 4 years all parameters are in range although I must admit to never checking ammonia.
All fish are fine and healthy.
 
The reason cat **** smells like cat **** is because of ammonia. Thats what gives it that... rancid... scent. Also some hormones but mostly ammonia.

If you are able to take a water sample out and that sample smells like cat ****, I'd be worried about your ammonia levels. Although if the fish are all healthy and showing no signs of stress... Not sure!

Are you 100% sure its from the water itself? Maybe a snail got out and died on the back side of the tank and it has rotted and wafted up?
 
If i put my head in the sump area it stinks if i put my nose over the rim of the display tank it stinks if i pull a sample of water our ina glass it does not smell? I did a 20ltr wc and siphoned water out of my wier area thinking there was crud at the bottom the water smelt. So not sure if it is a quantity thing?
I have put carbon in the sump, i have hung a bag of carbon in the air above my sump.
I removed my sump cleaned everything even painted the wood work frame and checked for mold, no mold that i could see.
Realy stumed on this one. My wife is complaining every day about the smell so i have to get it sorted asap!

Cheers.
 
An ammonia test kit isn't very expensive, and would answer if its actually the water or something else.

Maybe caked on residue on the lip/edge of the glass above the water. I don't know, I'm grasping there to guess what it could be. Lots of googling around on 'cat pee smell from aquariums' led to people saying its ammonia, but no one being told that replied saying they tested ammonia to prove/disprove the guess.
 
What do you mean that the tank smells like cat pee?

Does the tank smell like ammonia or does it have decomposing animal urine smell?

By the way, if you could smell ammonia in the tank, everything would be dead.

Look around the aquarium and sump for decomposing matter. Something might have hopped out and is rotting.
 
Going to test ammonia tomorrow will post results, as you say cant see it or livestock would be suffering.
Nothing has died had the sump out all spotless.
Can carbon dosing potentialy cause issues/smells?
Cheers

I am thinking that these observations are confusing :-)

To recap: The sump area has an odor (contains sump, skimmer, pumps, and the tank water). The aquarium has an odor (live stock, water, water from sump). Sample of water does not have the odor.

Conclusion: Observations are mistaken or the odor is not coming from the water.

Is the odor inside the skimmer collection cup?
 
No odor in the skimmer cup, trust me im confused.
Could it be the timber made stand, i varnished it at the time of construction. Maybe mold because of the damp enviroment, although i have had the sump out and painted the sump area and know signs of mold.
There was a slight damp area on the base of the stand which is made of chipboard, but if i put my nose next to that area there was know smell.
 
No odor in the skimmer cup, trust me im confused.

Odor not in a tank water sample nor being concentrated in skimmer. OK.

I would investigte the mold idea. Since this is around a saltwater aquarium, it might not resemble a terrestrial mold.
 
Hi

Had results back from lfs no ammonia and no detectable smell from a 500ml water sample.
Could be mold dont know what to do next though?
 
Probably not much help but I noticed that when I leave my reef crystals mix in the brute for to long it reeks of cat pee. Have you switched salt lately?
 
I have had an ammonia smell from my ro/DI brute before and tested none. Did some research and the best answer I found was bacteria. Do you have a large ATO reservoir in your stand?
 
Yes i have a large ato but i stripped down during sump clean.
No switch of salt so not that.
Can not believe more people have not encountered something similar.
Had a impeler magnet rupture recently on my protein skimmer pump metals in the water! Could this promote the growth of different bacteria that can give off a bad smell? Sounds far fetched!
