No polyps but still grows?

[KIKe]

Hello everyone,

I got this speciosa frag about 4 months ago. It had normal PE at first, but after a couple weeks I couldn't see lots of the polyps at the day time, only when lights are off.

It still grows and also has some pink. What could be the cause?

I think my nitrate is at around 0 for a while. Would that be the possible reason?

It could be the low nitrates, but acros can go dormant for months and then take off with growth and PE. Speciosa tends to be especially temperamental. The fact that it’s growing and has PE at night tells me it’s healthy. Any signs of pests? Have you ordered an ICP test recently? Any fish that could possibly be picking at it?

Thank you for the reply.

I did deal with the little white bugs a month ago, but it has been like that for a long while, way earlier than I had the bug. I did see some improvement on PE after dosing nitrate.
Hopefully it will show better PE at day time.

I think it might actually be the nitrate problem, my acros (especially my WD) weren't really happy due to strong light with low nutrients.

You have some very nice acros. That is very likely. If you don’t already, I would suggest dosing acropower. I noticed improvement in growth, coloration, and PE almost immediately after I started using it.

Oh wow, thank you.

I am dosing neonitro at this time. Will try other products after I use up this bottle. I also have AB+, isn't that pretty similar to acro power?

I use AB+ too. It’s a great product. Both are amino acid blends, but AB is more of a general blend for all corals. Acropower was made specifically for sps and acropora. My sps love it. I wouldn’t stop using AB+ though. I also dose Aquavitro Fuel.

I see, will definitely try that!
