Smelly Tank

[djbetterly]

I have a small frag tank plumbed into my display tank, they are in two separate rooms, and the frag tank has a bit of a funk....so much so the wife is noticing which isn't good. I'm curious what would make it smell, but not the display tank? I have one fish in there and a couple emerald crabs, but no snails. The frag tank has some live rock a there is a bit of GHA.

Any ideas why? And most importantly any ideas on how to get rid of the smell?

Activated carbon to get rid of the smell. How much flow is going through the frag tank?

there's quite a bit of flow, do you think it needs more?

I'll get the carbon going...

If the frag tank is in a smaller room with limited ventilation then the odor would be stronger there than where the other tank is. Carbon or Purigen are the best for removing odors. As for what is causing them, it's most likely out gassing from the nitrifying bacteria as they process the waste from your fish, corals, and inverts.

What is in the frag tank? Any used rock or sand that could be going through a cycle? Maybe both tanks smell but you just don't notice the other. Either way, carbon will remove the smell. I run carbon 24/7 and replace it monthly. It probably doesn't do much at the end, but it doesn't hurt to keep running it. It keeps smells away and the water from becoming yellow.
