I don't really smell my corals, but whenever I am doing a water change or looking at the sump, I get a really earthy smell of algae that punches me in the face and suffocates me until I leave

Kind of a weird title I know
Oh the mucus of some of these corals smell awful! Just had to move a ton of stuff for like the third time in three weeks because I am terrible at placing corals.
In my opinion, leptoseris is the worst, smells kinda like a summer garbage can.
What do yall think?
I actually was drawn into this hobby when I first started out and went into a pet shop with a buddy who was looking for a leash for his dog. They were unboxing a transshipment of fish and coral and I had to go over to the fish department to find out what was making the ocean smell that was wafting through the place? I saw all the amazing fish, yellow tangs and electric blue damsels and green bird wrasses and I was hooked.

That’s almost all true, but most of it was just an exercise in creative writing. So many times I have been in stores where people were complaining about the smells and I just celebrated that I had ruined my nose with nose candles in my wasted youth.

I have had a few mariculture acro colonies that had spoinid worms and out of water that smells like a mix of fresh frag and dead colony floating in a bag of its own rot mostly fresh frag tho ;)

This is a funny topic and ironically enough one that was the subject of conversation at a frag swap I attended a month ago. Corals all definitely have a very unique smell, a coral smell. I would not call it bad, but definitely unique. Acros certainly seem to have the strongest smell at least to me. Oddly I don't notice much when I take leptosteris out of the water. My cleanup crew is so robust that I have never had the pleasure of smelling dead snails. By the time I find them they are just empty shells....Hermit crab food.

I was away from the hobby for several years and returned 3 years ago. Being away for as long as I had been (15 years), my memories had faded as they tend to do, and I only remembered the beauty and wonder of it all.

When I returned to the hobby and brought home my first couple of frags the smell came out and a smile came over my face. This familiar odor was something that I didn't even know I had missed. This smell meant this is really happening again. I have been back at it for 3 years now, with 3 full tanks, and that pungent frag-rance still gets me all excited every time. That is the smell of new frags.

I love this hobby.

Not a coral, but I let my Caulerpa sit with some bleach before I flush it so it doesn't clog. This stuff needs to be banned by the Geneva conventions because you can probably make chemical weapons out of it. It doesn't smell remotely like something natural at all. The best way I can describe is a mix of organic solvents and melted plastic

One thing I do want to smell are Melibe sea slugs though. Apparently different species smell like watermelon, lemons, and other fruits
Why not feed the caulerpa to your fish especially if you have tangs? I grow different types of macro just for my tangs to have a natural and fresh diet.

I've been fighting a frag of waving hand anthelia that had made it from my 25gal to my 220. I'll pull out a rock is on to try and scrape it off with a wire brush only to have it return weeks later.

Anyways, that stuff STINKS! I gag every time I try to get it off my rocks.

It is kind of an expensive tool… one that measures the light level at different depth levels of light in your tank… it will help you determine the depth you should place different corals based on the light they receive in your specific tank. It allows you to place things where they like being. I have one : ) Yeah, I didn’t remember what it is called lol sorry… if you are talking about anemones… lol… those guys go where they want lol

I honestly don't go smelling them unless there's an issue. I was unaware that they smelled quite differently.

I'm just smelling for death.

You are talking about a par meter, not sure what that has to do with how corals smell though.
