I've done a search on this and didn't come up with any help. I have an established tank (6 months old now). Currently, I have no fish (going fallow for ich), and just 4 corals. I've checked my parameters, and they are as follows...
The only thing I have changed recently is that I added some chaeto to my fuge 24 hrs. ago.
Any thoughts? Should I be worried or let it pass? I've read some stuff on here about hydrogen sulfide.....it does smell a little. What, if anything, can I do about HS? TIA
