Polyps not opening

[hfabs]

Hihi

My readings as follows:-

PH : 8.2

Salinity : 1.023

Alkalinity : 8.6dKH

Magnesium : 1080ppm (low)

Calcium : 350ppm (satisfactory)

Ammonia/Nitrate: Undetectable

Calling on all reef experts for comments as to why my polyps aren't opening? Any advise?

Many thanks

Mark

can we know which polyps are you referring to?

If you are referring to zoas, did you buy the zoas when it's opening nicely at the shop and when you bring back it's not open for 2-3 days? zoas are quite hardy and your specs is enough to make it open... also check whether there is any "white dots" on the polyps itself / any insect alike on the polyps..

Photo will be best

Onizuka@ Thanks very much for your swift response.

Those not opening are: colony polyps, yellow zoas and now my bubble tip anemone are not opening as well. Will take photo tmr and post it here as I hv switched off the lightings and the corals are prolly in sleeping mode now.

CFOh@ thanks will check for nudis.

Thanks all

Hmmm do u have any non reef safe fishes? Maybe they r niping on the coral.

[hfabs]

I hv 2 blue tangs, 1 scopas tang, 5 anthias, 3 dartfishes, 5 spotted cardinals, 2 cleaner shrimps, 2 boxer shrimps and that's about it and I think they are reef safe and I have not seen any of them nibbling at the corals/polyps.

I did about 10% water change 3 days back but I don't think that was the cause. Still trouble-shooting, hiazzzzzzz

[Jameshong]

What is the PO4 level?

[dnsfpl]

blue tang are not 100% zoa safe

[hfabs]

Jameshong@ Thanks...good point and I have not checked yet cos I thot no algea Phosphate shd be okay. What shd I do if it is at critical level, apart from using solutions to reduce phosphate?

dnsfpl@ Thanks...will keep a close watch on the blue tangs.

Cheers

Bro wat water do u use for ur top up? If using tap water will cause PO4, better to use DI water. If PO4 is high, do weekly water change and can also try goodbye PO4 from Henry. Another important thing to check is ur NO3.

[hfabs]

Dreamlover@ the last top up I used Iwarna's top-up. Thanks : )

Hmm then should not be a problem, if I'm not wrong, Iwarna's top up consist of cal,mag and other useful supplement.

Hi CFOh@ thanks alot, I caught 7 nudis in the tank. Yirks...don't know where they came from. Do you know any medicine that I can pour into the tank to kill those that are still in the tank.?

Attached are my sleeping polyps.

Hi, Bro,I suggested Dip all your infected Zoas with Coral-RX. And get few yellow wrasses to control them for the moment..

[CFOh]

Pls find cartoon below on Coral RX application..

CoralRx - Don't Risk it. Dip it.

Try dip your rock of zoa in tapwater for 10 mins,could be some pest or nudi irratating your zoa,they will open by about 2 to 3 days.I dip mine and most recover after 3 days,gd luck.

[hfabs]

Predatorfish@ Thanks will do that tonite in fact i am getting Coral RX and if I can't get hold of it, I will bath them in freshwater. I have some tap water that I set aside for a few days now, I shd be using tap water that has been set for a few days right?

Thanks

I don't think it's advisable to add medication into your main tank to treat corals or fishes. Unless really really no choice due to some special circumstances. Best is to put in that extra effort to isolate them for treatment.

I use raw tapwater straight from tap,never leave them overnight to dip my zoa,lol. Zoa will be fine after tapwater dip,i,ve seen zoa grow in very polluted area with oil,lol!
