Bacteria bloom pulling the oxygen out possibly? Are your fish breathing heavily?

And Welcome to Reef2Reef! Wish it were under better circumstances but glad you came!

 

[twilliard]

yup! Bacterial outbreak. What is the PH like?

Welcome ot R2R! Glad to have you here.
Possibly a contaminant got in there? Got a cleaning lady? Or any air fresheners or cleaning products used near by? Children that like to play with coins or other things?

 

[Jorge8484]

PH is 8.2 and thanks guys

 

[twilliard]

Time for a 50%+ water change!

If your fish are breathing heavy or faster than normal you need to get more oxygen in the water. Bacterial blooms can really drop the O2 levels if that is what it is.

By chance have you tested your alkalinity? If you are CO2 limited you might have raised your alk without seeing it impact your pH.

 

[Jorge8484]

Fish look normal as usually doesn't like they are breathing heavy

I still would do a water change to try to lower that bacteria (if it is a bacterial bloom) need to get a sample under a microscope :)

 

[melypr1985]

water changes never hurt! Running carbon is a good idea and won't hurt to do either.... just in case.

i had crabs kick the bucket from an alk swing. Do you dose alkalinity or any buffers or anything for that matter. What are your parameters? alk, calc, mag, phosphate, nitrate, and temp?

Just did an alk test and this is what I got [emoji1369][emoji1369][emoji1369][emoji1369]

Welcome to R2R Jorge
How old is the system?
What are all your parameters
Ca ?
Mg ?
Alk ?
Po4 ?
No3 ?
Ph 8.2
Salinity?
Answers these questions and we will have a much clearer understanding of what is going on with your system.

Welcome! How long has the tank ben running?

 

[Brew12]

How's the tank doing this morning?

Have you been dosing alk, ca, mag lately? I was dosing daily for a week and one afternoon I came home and found my tank cloudy with lights on. Started panicking and immediate thought was mini cycle and ammonia! While trying to stay calm I noticed my fish were acting normal, corals were a little irritated, and snails were a little irritated also. Don't remember doing anything that would cause a mini cycle so I stopped dosing and just monitored and tank cleared in 3 days. My thought is calcium precipitation. I ordered new test kits and I'm anticipating really high readings...

Some coral heads are turning black and this set up has been up for about 6 months....

I'm guessing it is soft corals that are turning black?

Sounds like you may have a toxin in your tank. Are you able to run activated carbon as a filter?
