Corals dying/ not well


Griff

Recommended Posts

I recently lost my sps digi. My Duncan was by far the happiest coral I. The tank now he's been closed up for 3-4 days. His base used to be the brightest green. Almost like he was glowing. Now the base isstarting to brown out in places. My hammer doesn't extend as much as it used to. My recent fungia plate looks like it's browning out too. I do have a rainbow nem which has lost all color and is a dull pink. It's been a long battle trying to make the nem happy. He has had his mouth open the size of a nickel or quarter a few times and seems bloated at times and shrinks up other times. Something is going on in the tank as all my corals just don't seem happy at all. I do have some smal spots of Cyanobacteria but it's relattively sparse. I also have whitish grayish fuzzy stuff all over the live rock and on the glass. You have to look close to see it. It blows off with a blast of water from my turkey baster.

 

Could the struggling/dying nem be the problem?

Nitrates 0

Ammonia 0

Nitrite 0

Ph 8

Calcium 400

Phosphates 0

I do a water change 5g every week as I have 5 fish in a 30g

 

Fish

2 clowns they do host and I think are to rough on the nem for its size.

1 6 line wrasse

1 tail spot blennie

1 purple fire fish.

 

Tank has been going for 6 months maybe a little more.

I feed 7-15 pellets a day.

Feed mysis and brine 2 times a week.

 

Corals

2 acans

2 hammers

1 small fungia plate have had him 2-3 weeks

1 torch also not extending like normal.

1 sps digi dead

1 sps acro bleaching a little I've never seen polyp extension on him. I have had him 2-3 weeks

1 Duncan started with 3 heads now he has 8 but is all closed up.

 

I have a handful of hermits and snails as well.

 

I did 2 water changes this week because everyone seemed so unhappy.

 

 

My sand gets clumpy in spots and every week or so I stir it a bit.

 

Running 2 ai primes. I had all colors at 100% and whites at 90% to try and help the nem. It seemed to help at first but then he seemed to get worse so I cut them back to 80 for colors and 75 for whites.

 

Running a skimmer and I seem to be getting less skim than normal lately.

Sounds like the nem is definitely sick. I would turn down the lights even more as it seems like it could be bleaching out. I have had a BTA for a year now and I am just getting to a peak of 80% lights for a few hours.

 

If you have the means to run carbon I would probably do so to take out any possible nasties in the water being released by the nem.

 

If it were me, I would stop stirring the sandbed as well. That's going to release junk into the water. If you want to clean it, I would vacuum a small section every week with your water change, but never the whole thing.

The details above point to a low nutrient system, the corals might be starving.

Turn off all pumps and target feed all your corals.

Keep pumps off for 30 minutes.

 

Hope that helps.
