cloudy water on an established tank

[Dr.Nate]

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...

ammonia...0
nitrite....0
nrate...0
sg....1.025
kh.....7
ph....8.1
calcium....420

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

How long has the tank been fallow? Could be you've had a massive die off of bacteria.

Have you been feeding the tank? If so, with what/how often?

Cheers
Steve

HS smells like a rotten egg. Does it have any color

 

[Dr.Nate]

Oh, sorry....forgot to mention that I have 2 cleaner shrimp and about 10 crabs....so I've been feeding 3 times per week for them only. There is no "color" to the water, but it doesn't have a real strong odor either. Just mild odor. The only other thing I changed (since it's been fallow) is that I added a sump/refugium, but that was about a week ago. Any help?

 

[steve-s]

Have you been feeding what you normally would have with fish or an appropriate amount for 3 shrimp?

There's a big difference between the two and the needs of the bacteria.

Cheers

[Dr.Nate]

yes, I've been feeding what I normally would for fish, etc....I have never changed the schedule...3 times per week even without fish due to massive appetites of shrimp and crabs...ha.

 

[steve-s]

Nothing is standing out then really. The chem doesn't support a precip event, feeding would suggest the bacteria would be sustained more or less and chaeto does not release sexual material/caulerpicins.

The only two things left are heat causing massive bacterial reproduction or sediment/dust possibley from the new sand in the fuge?

Cheers

Thanks, steve....I'll check the temp.....haven't looked in awhile. Don't think it's sediment, that only last a day or two.
