SPS not looking good all of a sudden

[Bent17]

Hi all,

I have just noticed that some of my SPS is not looking normal. I have my Pikachu all of a sudden the middle part has no polyps showing and also some other sps are not showing as usual. I noticed also my zoas were full covering the rock and now they look like half disappeared.

P04: 0.05
N03: 9.0

Salinity and temp? Do you have any leather corals?

Raise your po4 or lower the no3.
Check you have plenty of flow.

Thought that thats a good range. been like that for ages

Have you checked flow since you have had growth?

I run higher but you are ok. Run carbon and do a water change in case something got into your tank.

kept it pretty much the same

The numbers you’ve posted look good to me. Have you had a recent change in lighting or flow? Do you have a new critter? Can you check ammonia in the event that you’ve had a spike? Are you using tap water or RODI?

Growth=less flow.

RODI TDS 0
Lighting I changed the schedule to a much powerful one for like half a day and reverted back as it elevated my tank temp

SPS shouldnt have more flow to be healthy?

How stable has the alk been? How often do you test?

 

[Bent17]

I test 4 times a day with my KH Keeper+

Yes, exactly. What I meant wasn't clear.
You had more growth, that growth inhibits the flow, the inhibited flow equals less flow to the coral.
Sometimes you have to up your flow because of growth.

but could that have effected the corals decrease in flow? the zoas are at the bottom and you can see the difference, the pikachu and the other green one are right next to the mp40s so they have enough flow I believe

How long ago were they exposed to the high lighting levels?

Bit over a week ago and was for less than a day as I reverted back

Looks like your tank is pretty stable and acros can be particularly sensitive to changes in lighting so I can see how a “sunburn” effect might show up a few days after such a change.

Unfortunately I would just keep an eye out and add some carbon in the event that something unwanted that you can’t test for got into your tank.

Good luck! Let us know whether things change.
